It’s fun to watch the wacky situations our sim counterparts get themselves into… or the situations we force onto them for our amusement.

The Sims 4 offers an interaction between sims where they can exchange their phone numbers with one another. However, even if you haven’t completed this interaction, you can still call a Sim – as long as you have some kind of relationship with them. In Sims 4, a ‘0’ relationship is neutral. 100 is the maximum positive relationship two sims can have, while -100 is the most they can possibly hate each other. I have added a new feature for my Sims 4 Family Management Cheats mod: Extended Family Recognition! Now your Sims' extended family members throughout the whole family tree can be recognized! (Well, up to a certain depth level, there had to be a limit.) All relatives will get a 'Family' relationship bit that can be seen in the relationship panel. While there’s a lot of places to visit and activities to enjoy in The Sims 4, there’s always room for some improvement. And more autonomy is always good. The Explore Mod by KawaiiStacie lets your Sims go out and explore the world autonomously, either alone or with friends.

But The Sims contrasts substantially with human life in its cartoonish nature. Everything is funny, absurd, and sims just take everything as lightly as possible. For them, life is simple.

Well not anymore! Thanks to the tireless work of some amazing modders, we can re-introduce some of the more nuanced aspects of human life into the game, increasing the simulation’s complexity and often making everything just a little bit darker, grittier… more real.

For anyone interested in making their Sims experience as real as it can be, here are the some awesome mods for increased realism.

20. Realistic Reactions

Have you ever been cheated on?

Hopefully not, but let me tell you it isn’t chill.

For this reason I always found it unrealistic that sims would just get angry at their cheating spouse for a little bit before returning to normal, at least whenever infidelity was actually discovered.

Creator Scaldwellhu agrees. And they made a mod to make cheating as big a deal as it usually is in real life.

Now couples will be devastated by the event, and it’ll take a lot of work to get things back in order. Even the kids will feel upset when their parents are in this situation!

19. Miscarriage Chance

Pregnancy is a beautiful process. But sometimes there are complications, and that’s just a fact of life.

This mod by LittleMsSam introduces a slight chance that one morning, a pregnant Sim may wake up with cramps and abdominal pain, prompting them to go to the hospital.

While sometimes they’ll come back with a healthy baby and make everyone in the household relieved, more often than not they’ll return with dark news despite the doctor’s best efforts.

It’s sad, it’s dark, and it’s incredibly realistic.

Now on the flip side, if you want pregnancy custom content that’s a bit more light-hearted take a peek at our pregnancy mods list. Not as much realism, but a whole lotta fun in there.

18. Pregnancy Overhaul Mod

Creator LittleMsSam doesn’t just want to put a damper on your reproductive fun.

She just strives for realism, which we can find in her Pregnancy Overhaul Mod.

Not only does it replace the absurd pregnant belly size found in vanilla for something more anatomically correct, but it removes the exaggerated pregnant walking animation as well.

It also lets expecting sims continue practicing yoga, swimming, and other such activities up to the beginning of their third trimester, as is normal for would-be-moms in real life(which I had to Google to confirm, I mean I’ve never been pregnant so…)

17. Risky Woohoo & Try For Baby Chances

Normally you can actively choose whether you want a sim to have safe Woohoo with a partner, or outright try for a baby and get them pregnant.

But that’s not quite how it works in real life.

Modder PolarBearSims came up with some tweaks to make the Woohoo experience more immersive by replacing it with Risky Woohoo, and implementing a complex fertility system affecting all sims.

Depending on their fertility levels, location of the encounter, and some other factors, some sims will have more of a chance of becoming pregnant accidentally than others. Sims may also become infertile, requiring them to get fertility treatments to actually get pregnant. If that isn’t real, I don’t know what is.

16. More Best Friends

I’ve never been able to give a definitive answer when someone asks who my best friend is.

I would never be able to pick just one. They’re all key parts of my life!

Thanks to creator LittleMsSam, your sims won’t have to pick just one either.

Now the “become best friends” interaction will have a 30-minute cooldown rather than a one-time use, allowing you to create inseparable squads of Sim besties.

15. SNB – Sim National Bank

The way money and bills work in The Sims 4 is pretty basic for a game made for simulating human life.

The Sims 4 Realistic Relationship Mod

Sim National Bank by SimRealist is an in-depth mod that endeavors to overhaul the financial system in TS4, letting sims manage bank accounts, take out loans, pay their bills individually, and so on.

The Sims 4 Relationship Mods

Quite honestly, this is one of the most realism-enhancing mods I’ve ever seen.

But only the most hardcore players will actually have fun introducing accounting into their sim lives, which is why I don’t place it higher in this ranking.

But let it be known, this mod is exceptionally realistic.

14. Personality Please!

Sims are notoriously less complicated than humans. They take life one day at a time and often choose what feels right in the moment, rather than what makes sense in the long run.

Personality Please! by PolarBearSims is a mostly romance-centric rework that makes Sims considerably less promiscuous by making traits, aspirations, and past events greatly affect their relationships with other sims.

Now they’ll actually need to be compatible if you want them to get down and dirty.

Other than that, the mod also gives cats and dogs more varied personalities, and sims can learn traits and choose careers just from having deep conversations with others. How cool!

13. Automatic Beards

Ever since I turned 14 years old, my ever-growing beard has been an important part of my life.

Every morning I decide whether or not to shave, and the choice has important ramifications on how my life plays out. The same should be true of our digital friends.

This mod makes sim beards grow automatically over time, requiring constant shaving. Unless you want your sim to become Gandalf the Grey, that is.

12. SimDa Dating App

Dating and finding partners is astoundingly easy in Sims 4 compared to real life. Which is why we needed dating apps, and they don’t – until now.

The SimDa Dating App by LittleMsSam works a lot like a streamlined version of Tinder, allowing your sims to schedule meetings, set up blind dates, or simply call somebody over for a one night stand.

Each of these interactions has its own interesting features and possibilities.

You can start relationships, have some fun… and even get someone pregnant by accident. Just like real life!

11. The Explore Mod

While there’s a lot of places to visit and activities to enjoy in The Sims 4, there’s always room for some improvement.

And more autonomy is always good.

The Sims 4 Family Relationship Mod

The Explore Mod by KawaiiStacie lets your Sims go out and explore the world autonomously, either alone or with friends.

They’ll have adventures, gain skills, meet people, and maybe even change their world view!

This mod adds several entertaining activities like gambling, getting your nails done, doing temporary work for an extra buck, and even going out to get takeout if you’re too lazy to cook. All very realistic and very immersive.

10. Height Slider

One of the most frustrating and unrealistic things in the game is how every sim is exactly the same height as others of the same age group.

Well thanks to this mod by creator Luumia, you’ll be able to give your sims different heights through a slider in CAS.

Everything else will, of course, scale proportionately to height.

As a bonus, Luumia included a hip shape slider and neck length variation for even more Sim variety.

9. Extreme Violence

The world is a very violent place, and even peaceful suburban areas like see their fair share of violence from time to time.

Extreme Violence by Sacrificial Mods adds the possibility for wrongdoing sims to attack others in a wide variety of ways.

Shooting them with machine guns, cracking their necks, chopping them up with a machete, and even crushing their skulls by sitting on them are only some examples.

I mean, I guess it’s realistic?

Not only does it add the acts in themselves, but a bunch of added functionality revolving around them, like the possibility for sims to acquire the Serial Killer trait, or paying a gang to off someone your Sim doesn’t like. Yikes!

8. Meaningful Stories

Sims don’t take life too seriously, and they’re incredibly fickle.

They may be completely devastated by the death of their pet one moment, then ecstatic because they watched a good movie the next with no in-between.

This mod by Roburky reworks the mood and emotion systems to make them more nuanced and realistic.

A depressed sim will need time and help from their friends to get out of a rut, and something like a first kiss will make them feel happy like never before.

Transitions between emotions also take time, and there are transitional periods when they’re feeling a bit of everything.

7. Passionate Romance

The romance system in vanilla TS4 is pretty basic.

You can flirt, go on dates, Woohoo and get married, but it never really feels like a relationship.

Passionate Romance by Sacrificial Mods improved this greatly by adding several new interactions like snuggling, hugging romantically, taking a romantic selfie, and even grabbing each other’s butts like they used to in TS2.

6. After School Activities

Going to school has never been just about learning history or science.

It’s also about making friends, acquiring skills, and finding yourself.

With this add-on by amazing creator KawaiiStacie you can add all these things. It endeavors to flesh-out educational experiences by adding over 30 after-school programs for children and teens.

Examples include the Anime Club, the Yoga Club, band, and basketball.

Sims partaking in these activities will learn skills, make friends, gain motives, and may even apply for scholarships depending on their performance throughout their school life.

5. Wicked Whims (NSFW)

If there’s something humans never get tired of, it’s sex. We love it, and so should our Sims if we’re to have a realistic experience in-game.

Wicked Whims goes a long way to develop everything sex-related in TS4, from turning the Woohoo interaction incredibly graphic to giving female Sims a fully-functional menstrual cycle complete with mood swings, cramps, varying fertility and a need for pads and tampons.

This one goes deep.

It even introduces contagious STDs! Now if that isn’t seriously realistic, I really don’t know what is.

4. Basemental Drugs

Alcohol and other drugs have been a reality of life since time immemorial, and that’s not about to change anytime soon.

Basemental Drugs endeavors to introduce this reality of human life into TS4. It lets your sim pals acquire, consume, and sell alcohol, tobacco, cannabis, and many other mind-altering substances.

Sims engaging in these activities may become addicted, have problems with the law, get arrested, and even go to rehab… and that’s only the tip of the iceberg.

It’s not pretty, but it is the real world.

The Sims 4 Polyamorous Relationship Mod

3. Basemental Gangs

If you like Basemental Drugs, the Basemental Gangs expansion is sure to pique your interest.

It fleshes out the entire drug dealing aspect of the mod, allowing you to create a criminal empire and become the leader of one of four gangs.

Again, dark but quite brutally realistic.

You’ll have underlings, earn loads of blood money, and there’s even an entire skill system to become a better thug. It may not be wholesome, but it sure as hell is realistic.

If you’ve ever wanted a little more GTA in your Sims experience, this mod is the ultimate crossover.

2. Life’s Tragedies

As you may have realized by now, not everything is glitter and candy.

There are tragic and difficult moments in everyone’s lives. And they can arrive when you least expect them.

Life’s Tragedies by Sacrificial Mods adds a wide variety of possible tragedies that may befall your Sim or NPCs close to them. Like randomly being run over by a car, getting jumped by a homicidal maniac, or even contracting a life-threatening disease they’ll need surgery to overcome.

It may seem a bit intense, but don’t worry. You can control how often these tragedies happen, so you can either turn your Sim’s life into a horror story or just inject a tiny bit of dark realism into your game.

This will be absolutely hilarious, devastatingly upsetting, or some kind of in-between, depending what you’re looking for.

Just note the download page includes a lot of other mods from this creator, so look towards the lower part of the screen for their “Life’s Tragedies” download file. It does get updated from time-to-time so if you want the absolute newest version definitely grab it from the link above.

1. Slice of Life

Easily the most comprehensive and complete realism overhaul for The Sims 4 is Slice of Life by KawaiiStacie.

It’s an extensive mod that touches almost every aspect of life in the game.

Your sims get visible emotions, recurring memories of past events that’ll affect their moods, a complex fitness system, and reactions to their own appearance. Among many other things!

One of the most impressive features of the mod is giving every single sim a personality based on the Myers-Briggs 16 personalities test, which affects the way they behave and interact with other sims to a great extent.

It also adds many features we’ve already seen in previous mods such as functional alcohol, serious sickness, and a complex menstrual cycle, all in a single polished CC pack affecting every sim in your world, including NPCs.

This is truly the ultimate realism mod for The Sims 4, hands down.

If you need a one-stop shop realism mod then give this a try before anything else. You’ll be surprised how much it offers.

1.) Break Up Anytime– Lets Sims breakup with each other, no relationship decay needed!

2.) Communal Showers– Lets children and teens to shower in the same room as others (say for instance a Gym shower)

3.) Extended Family– Allows the game to recognize great-grandparents, second cousins, great aunts/uncles etc as family.

4.) In Laws Fix- You know how when your sim gets married their parents always try to hit on the new spouse? That is because there is a bug where the new spouse considers the parents family but the parents don’t consider the new spouse family.

5.) Met Great Grand Child– With this hack, sims will get a custom memory when they have great-grandchildren, similar to the one they get when they have grandchildren.

6.) More Useful Apologies– This replacement is reprogrammed so that when you instruct a sim to apologize, if the apology is accepted any “furious” state is wiped out, and their relationship is reset to just above zero, (or higher if they got on well before they became furious). Gives them a chance for a real fresh start.

7.) No Friendship Loss Notification– Great for those whose Sim has a ton of friends/relationships but don’t really want to be bogged down with all the notifications when they fall under 50.

8.) Relationship Remover– Sometimes you didn’t want your Sim to meet another/have contact or just to lose contact with another Sim. This lets you do that. Does not erase memories made with them.

9.) Sibling Torment for All– The Fight…/Torment interaction introduced by Apartment Life can only be done by blood-related siblings. This mod expands it so it can be done by children and teens who are not siblings as well, to satisfy wants or just to have another interaction

10.) ACR- Autonomous Casual Relationships– This is a great mod and don’t think just because it’s #10 it’s low on the list! This mod makes social and romantic interactions more possible than Sims on their own. It is a big mod so use with care.

11.) Same Sex Marriage- This mod replaces joined unions for same sex couples with actual marriage. It affects all the relevant interactions, wants, fears, and memories

12.) Easy Sofa Global Hack– This is a simple global hack which enables sims to have romantic interaction more easily. Relationship points doesn’t matter. Sims will not reject romantic relationship even if they don’t like each other.

The Sims 4 Modify Relationship Cheat

13.) Easy Bed 091117– Easy bed is an object which enables users to customize romantic interaction level between sims depending on user’s preference. Also you can turn on / off privacy and so on. This is not a global hack.

14.) Last Name Copier 0807070– LastNameCopier is a simple tool object with which you can copy surname between sims easily.

15.) Woohoo Count Fix– The way the game counts a sim’s Woohoo memories is flawed. The game has wants such as “Woohoo with 10 Different Sims” and so on, but the game does not even check the subject sim when counting these memories. It simply counts all the Woohoo memories a sim has, despite the fact that a sim can woohoo with the same sim in different types of woohoo, such as Public Woohoo or NPC Woohoo. This means that you can easily achieve many of the Woohoo wants without actually woohooing with the required number of sims, making the Woohoo wants easier to achieve than Make Out wants, which are counted properly, because there is only one kind of Make Out memory.

16.) Found Family– Do you have sims who are raised by more than two parents, but annoyingly the game does not consider the non-biological parents to be family? Or “siblings” who were raised together but don’t technically share parents, so the game doesn’t mark them as family? Or just sims who are really close and ought to be able to use Family Kiss?

17.) “Met New Great-Grandchild” memory– I guess EA never imagined sims would live to see their great-grandchildren (even though they gave us resurrection and vampires and elixir of life!). With this hack, sims will get a custom memory when they have great-grandchildren, similar to the one they get when they have grandchildren. Its made this to go along with my extended family hack, which will also allow family interactions between great-grandparents and great-grandchildren, but this actually doesn’t require it.

18.) Sibling Torment for all– The Fight…/Torment interaction introduced by Apartment Life can only be done by blood-related siblings. This mod expands it so it can be done by children and teens who are not siblings as well, to satisfy wants or just to have another interaction. There are three flavors.

19.) Relationships Panel Remover– This is a cloned Gnome. I added option “Relationships Panel Remover” which allows you to remove unwanted sims in your “Relationships Panel” screen. This hack will not affect memories and relationship scores, it will just simply remove them from your panel and they will appear again once you make a conversation to them. But it will affect your telephone directory and email address book, the sims that you removed will not appear there and they will appear again once you make a conversation to them.

20.) Gender preference– his mod slightly alters the way gender preference works in romantic socials. EX: A gay male sim will not try to flirt with another male sim, even if both are in love each other, unless the target sim is gay or bisexual too.
With this mod, the gay sim will flirt autonomously with target sim, either he’s gay, bisexual or straight.

21.) Make out _IS_ a romantic social, dammit!– Bug existing since the base game: while all the other kisses trigger the crush or love in sims, if their relationship points are high enough, the make out one does not.This fix resolves the issue.

22.) Marriage: Last Name Chooser– It’s like ChristianLov’s except this happens when you are at the alter getting married. Not sure if the two conflict but I would just pick one.

23.) Romantic Flags Batch Cleaner– This mod is similar to others like the Sim Manipulator except this can wipe out all relationships in one fell swoop if so desired.

24.) No Jealousy Unless Married/Engaged/Going Steady– Will make it so that only sims who are married, engaged or going steady will be jealous of one another, other sims will not experience jealousy no matter the level of their LTR and STR.

25.) Marriage – No Name Change– Normally, when two Sims get married, the new couple takes the last name of the Sim who requested the marriage. This mod changes the behavior so that no name change occurs.

26.) Gender Preference Adjuster– Oudated with ACR but useful if you don’t want or can’t use ACR.

27.) Bisexual Influence Fix– When you use influence on a bisexual sim in an unmodified game, you can direct romance at sims of only one gender. The game looks at the bisexual sim’s gender preferences and picks the higher, populating the influence list with only men or women. My mod allows bisexual sims to choose from either.

28.) Less Jealousy–

• Dates – Sims on dates will always become jealous regardless of relationship. If you go on a blind date, and the other person spends the evening flirting with the waiter, it’s probably not going to go well.
• Threesomes – No jealousy if everyone involved is in love. Specifically, if sim A and B have a romantic interaction observed by Sim C, and Sim C is in love with both Sim A and Sim B then there will be no jealousy.
• Commitment – Other than the situations above, sims will feel jealousy only if going steady, engaged or married.

29.) Less Naked Freakout– Sims will no longer freak out when seeing their lovers naked. The mod specifically looks at sims who are in love. Ideally it would instead look for woohoo memories, but that’s more complicated and ultimately not really worth it.

30.) Makeout Want Fix– Sims initiating make outs get the make out want satisfied at the beginning of the action rather than at the end.

31.) No Auto Dance Kiss– Sims won’t do the dance kiss interaction autonomously. Player can still direct sims to do it.

32.) No Hidden Woohoo– Visitors will no longer leave when residents have woohoo.

33.) Relationship Decay Fix– Fixes bug which causes game to error out when calculating the 4 pm relationship decay on very large families.

34.) Stop Kissing Me– Sims will no longer kiss when greeting or saying goodbye unless the relationship is crush or love.

35.) Fall out of love automatically when LTR is below 70– This mod automatically clears the love & crush flags if a sims str/ltr falls below 70,it also prevents the loosing a friend messages from popping up.

36.) Smooth Talk Interaction Enabled– This mod enables the smooth talk interaction for all sims.

37.) No Autonomous Cuddle Under Stars– This mod prevents sims from autonomously cuddling under the stars/clouds.

38.) No Autonomous Suck Face– As requested. One of the lamest romantic interactions to date, methinks. This should stop your Sims from sucking face autonomously.

39.) Fun Gain While Making Out– Because pixel people need to have fun making out too.

40.) No Autonomous Dance Kiss– This mod prevents sims from autonomously doing the dance kiss interaction.

41.) Adults Go Steady– With a friendly breakup option enabled.

42.) Asexual ACR Plugin-With this mod, if a sim has an ACR token that has been flagged “No Woohoo Allowed” (one of the options under “Autonomy”) that sim also won’t roll woohoo wants. Mainly meant for playing asexual alloromantic sims, who you want not to roll woohoo wants for their romantic partner(s) (or in general, but depending on the sim’s aspiration you might not have seen very many generic “have woohoo”/”have very first woohoo” wants anyway).

43.) “Ask to Leave Partner” Social-It appears between two sims in love if Sim B is engaged/married to someone else. If Sim B loves their partner and has a stronger relationship with them than Sim A they’ll reject Sim A, otherwise they’ll agree and, if their partner is on the lot, they’ll go break up with their partner right away.

44.) A More Realistic Romance System– DSS (“Dark Side Of Sims 2”) consists of three interacting components: a) modified relation behavior, based on attraction (called SRM = Sims Relation Manager) b) teen-adult relations, including teen pregnancy (called TAM = Teen-Adult Manager) c) more difficulties, more diseases, more deaths, more breaking objects, all based on both random dice rolls and sims’ / pets’ personality (the actual “DSS” itself)

45.) Confess To Cheating Social-Sims who have a “had an affair” memory with no following “got caught cheating” memory can “confess to cheating” to their “steady”/fiancee/spouse. It leads to a relationship drop (both between Sim A and Sim B, and between Sim B and the sim Sim A had their most recent affair with – eg. if Don confesses to cheating on Cassandra, she’ll wind up furious with Nina because that’s the most recent person Don remembers having an affair with), and “caught cheating/got caught cheating” memories. Depending on personality, Sim A’s charisma, Sim B’s STR/LTR towards Sim A, and Sim B’s history (i.e. have they had a partner cheat on them before and known about it), Sim B may forgive Sim A and experience a small relationship drop, or be left furious with a large relationship drop. A lot of this – relationship drop, how big an affect various factors have on whether or not Sim B forgives Sim A, etc. – are BCON tunable. It’s non-autonomous.

46.) Develop Crush/Love-Sims have an option to “develop crush/love” on other sims of the same age group (teen-to-teen or adult/elder-to-adult/elder), which will set the “crush”/”love” flag and also trigger the crush/love FX (sound effect, floating pink hearts above their head). It’s one-sided, so you can make an unrequited crush/love if you want.

47.) Friendly Break-Up– There are three outcomes: “bad breakup” happens if Sim A has poor relationship with Sim B (dictated by STR, because I figure a bad breakup can be very heat-of-the-moment so it’s how Sim A feels about Sim B in that moment that should matter). If Sim A has a good relationship with Sim B they’ll try to be gentler and use the OFB lay off employee animations: if Sim B’s aspiration is good they’ll take it relatively well and just be disappointed, but if it’s bad they’ll be angry. If they take it well Sim B won’t run off to cry or move out and their kids won’t react – everyone still gets memories so they might have a cry later, but it’s a lot less dramatic.

48.) Go Steady Memory Edit– Changes the memory text to “My sweetie’s all mine now! Is this true love? Time will tell…”

49.) No Cuddle Under Sheets-Disables the cuddle under sheets interaction introduced in AL.

50.) No Cuddle Under Stars On Floor– Now the “cuddle under clouds/stars” invisible marker thing that tells sims where to lay down can’t be placed on flooring.

51.) No Engagement/Marriage Wants Toward Non-Crushes/Loves-Your sims will not roll wants to get engaged to or marry sims they don’t at least have a crush on.

52.) Tuck In Love/All-Enables “Tuck In” between sims if Sim A is in love with Sim B. Also comes with a version that unlocks tuck in, allowing you to direct your sims to tuck each other in if the requirements for the interaction are met.

53.) Go Steady for Adults + Last Name Dialog– Combines two mods into one so you can now ask adults to go steady and have the same last name dialoge when getting married/joined union. Also changes the animation features of asking to go steady and some romantic hug.

54.) Romantic Standard Plug In– This is an add-on to this huge and frequently updated mod called Romantic Standards that replaces the jealousy checks in that mod to only happen if Sims are either on a date, or are in a committed relationship (Steady/Engaged/Married.
