** ''[[VideoGame/HarvestMoonAWonderfulLife A Wonderful Life'' (and AWL: Special Edition) requires you to betroth a girl and have a baby in order to advance the story and arbitrarily has the bachelorette with the highest affection towards you propose to you, if you aren't already engaged at the cutoff point. If you haven't gone after one girl specifically, you'll mostly likely get Celia to propose. You get a NonStandardGameOver if you say "no".

* ''ComicBook/ScottPilgrim'' - It's worth 9999 EXP and a free perk, anyways.

* In ''FanFic/ConversationsWithACryptid'', Izuku sasses All for One with this, telling him that he hasn't ground enough reputation to unlock the answer a personal question, and that if he gets enough, Izuku will tell him his tragic backstory. [[spoiler:In the last chapter, after saving Izuku's life, All for One asks Izuku for that tragic backstory.]]

* ''Webcomic/WhatsNewWithPhilAndDixie'' had a long-running gag where Phil and Dixie would get interrupted just before they could get to discussing "Sex in D&D" (presumably with illustrations). So when they finally got around to it, it showed a game session where the GM skips over the part between the player's character following a tavern wench upstairs and the next morning, awarding him 5 XP. The last panel has the infuriated audience's BigWhat visible from the Moon, which is where Phil and Dixie are hiding.

Usually, the explanation for how hitting on people could ''possibly'' make you more powerful is that your AppliedPhlebotinum weaponry is powered by [[ThePowerOfLove intense emotions]]; sometimes this is coupled with the idea that you're fighting a [[EnergyBeing Being of]] ([[IncrediblyLamePun Im]])[[EnergyBeing Pure Thought]].

* In ''VideoGame/{{Turgor}}'', if you open Sister's hearts, they will allow you to go in their chambers and travel to other sisters. It is also implied that the chambers of a happy Sister give more Color. However it is subverted [[spoiler:when you find out that giving Color to a Sister heavily damages their realm due to the sheer amount of it you need to use, which will actually decrease the amount of Color you can get. This will eventually lead to the Scorpio appearing, which will completely destroy your gardens.]]

* ''VideoGame/DwarfFortress'' used to be an example. Before, dwarves gained skills by hanging out with friends and lovers, and skill boosts will arbitrarily make dwarves stronger (even though this makes no sense for social skills). Thus, that dwarf that slouches in your dining room all day partying and making friends with everyone could very well be more dangerous than your elite military. Now skills only raise related attributes, but you still get such gems as fishing, studying, medic skills, and book keeping improving a dwarf's accuracy with a crossbow and Intimidation and Comedy ''letting a dwarf run faster''.

* In ''LightNovel/SwordArtOnline'', people who are in a close relationship can share each other's inventory. If they are married, their inventories merge.

* Major part of ''LightNovel/MagikaSwordsmanAndSummoner'' as the higher the hero Kazuki raises his relationship level with the members of his BattleHarem the more of their powers he can access for himself.

** ''VideoGame/GrandTheftAutoIV'' likewise provides three potential girlfriends for Niko (outside of the plot-mandated ones). Respectively, they can be called up for a health boost, wanted level removal, or discount on clothing once their relationship level is high enouch.

* ''[[VideoGame/ExaPico Ar tonelico]]'' is a series of pseudo-dating-sim-esque {{RPG}}s practically built around this trope, as you gain most of the game's [[MagicMusic musical spells]] by "diving" into the female characters' inner mental worlds and helping them fix their issues, an act which the game specifically links to romance. Furthermore, the characters' power in battle is increased by "Harmonics", a set of two gauges which represent the feelings of the fighting party and the magical songstresses respectively, which add status boosts to the party when the bars meet in the middle; the bars increase when the fighting party defends your singer-mage, attacks on her behalf, or does something otherwise suitably impressive for her.

* In ''VideoGame/{{Fallout 4}}'', maxing out a companion's Affinity and completing their personal quest will grant you a unique Perk that persists even if that companion is not in your party. If you choose to romance that companion, resting on a bed while they are nearby will grant you a "Lover's Embrace" perk, which increases the value of experience gains for a limited time.

* In RealLife, marriage (but not anything else) unlocks lots of special rights and financial bonuses that make it easier to get a high score and a better game experience, but also some rules and restrictions. For female characters, it also makes pregnancy and being over a [[ChristmasCake certain age]] much more acceptable depending on the server. Won't [[spoiler:prevent death]] but makes you less pitiful during it. You should check your stats and server rules to determine whether you'll pay more taxes, or whether you'll risk [[SoLongAndThanksForAllTheGear losing half your stuff]] if [[YouLoseAtZeroTrust the marriage breaks down]]. Some servers have implemented a GayOption patch.

* A core mechanic in ''[[VideoGame/Miitopia]]'', where your Miis have Relationships that can be leveled up to grant powerful team abilities, such as [[CombinationAttack team attacks]], self-reviviving through HeroicResolve when an ally falls, and taking extra attacks out of turn order to avenge fallen teammates.

** In ''VideoGame/RuneFactory3'', the higher your friendship/love points with a villager, the longer they'll stay with you when in the dungeons (At the lowest level, they'll bail out after 5PM, then 8, then Midnight). Your wife will stick with you no matter how long you stay in a dungeon (VERY helpful when slogging through the last couple of BonusDungeons).

* ''VideoGame/GrandTheftAutoSanAndreas'' has this. Six girls you can date, in exchange for perks, like weapons, clothes, their cars, the possibility for dying/getting busted without losing all weapons, and, in one of the girls' case, a plot advancing MacGuffin for a mission.

* In ''VideoGame/IWasATeenageExocolonist'', {{Friendship Moment}}s often reward the MC with powerful cards, and successfully dating someone after maxing out their heart meter also gives them the Smitten status, which increases all Social Skill gains by 1 for three months.

* In ''Die Fugger II'', a simulation game based on medieval European commerce, you were expected to take a spouse and sire a child. At certain points in the game, your character would die, and if you had an heir, the game would continue; otherwise, it would end.
* ''VideoGame/DeadInVinland'' has this, and it's all over the place because your party is a LoveDodecahedron. Numerous pairs of characters can get the "In Love" buff, which has several stat benefits (though also a penalty to Concentration-related [[StatGrinding skill XP]]). There are also a few other one-sided buffs like [[AnguishedDeclarationOfLove "Love Confession"]] and "First Kiss." Some characters can even get ''debuffs'' if they're rejected.

* ''VideoGame/NetHack'' players can receive substantial good or bad effects from sleeping with [[HornyDevils succubi or incubi]], but with proper preparation they'll almost always be positive. This includes permanent stat gains and instant level ups, and if you have a method of generating many such demons can be used to vastly inflate your max hit points even after you reach level 30.

* ''VideoGame/PlanescapeTorment'' is a strange case. You can get useful items or stat increases from, or confer stat increases to, almost all your party members by talking to them. The only real exception is Fall-From-Grace, who in a more conventional game would have been a potential romantic interest, but she can help you understand your party members better, cluing you in on which dialogue options to take--and also doing so earlier than the game would normally allow. Annah, meanwhile, is deeply attracted to you; you have the option to kiss her at one point, and it boosts her morale--until she gains her next level, where it returns to normal, possibly due to a bug. (For context reasons, let's now reveal that Grace is a [[HornyDevils chaste succubus]] and Annah is [[HalfHumanHybrid descended from fiends]].)

* In VideoGame/{{Turgor}}, if you open Sister's hearts, they will allow you to go in their chambers and travel to other sisters. It is also implied that the chambers of a happy Sister give more Color. However it is subverted [[spoiler:when you find out that giving Color to a Sister heavily damages their realm due to the sheer amount of it you need to use, which will actually decrease the amount of Color you can get. This will eventually lead to the Scorpio appearing, which will completely destroy your gardens.]]

* In ''VideoGame/BaldursGateII: Shadows of Amn'', romancing Jaheira the "right" way gets ''her'' a Harper Pin, which grants several useful bonuses. While better replacements show up near the end of the game it's a good item for most of the mid-game. More importantly, however, successful navigation of this quest (which is not actually part of the romance, but gets powered up if you're in a romance with her and weaves in and out of it), nets you a few large buckets of experience points. The trope is inverted (though it's perhaps more of an oversight) in the expansion pack ''Throne of Bhaal'', where if you're romancing Viconia you can [[spoiler: convince her to perform a HeelFaceTurn]]; doing so ''prevents'' her from using a very good item that she's already wearing--and she doesn't get a replacement to reflect the change.

** Incidentally, "diving" at level 5 and beyond is when things get ([[GameplayAndStorySegregation supposedly]]) dangerous. And any and all innuendo before this is blown out of the water [[spoiler: as their "inner" selves quite literally jump the [[CelibateHero protagonist]]. In a bath towel, a Y-shirt or as a succubus.]]

** Also, if your relationship isn't high enough with any of your teammates (if you haven't finished all of their character quests and talked with them in the final chapter) then you'll end up with the bad ending, as [[spoiler: the only reason Vayne doesn't go through with his original despair-driven suicide is that the character you have the highest RelationshipValues with snaps him out of it]].

* In ''FanFic/ConversationsWithACryptid'', Izuku sasses All for One with this, telling him that he hasn't ground enough reputation to unlock the answer a personal question, and that if he gets enough, Izuku will tell him his tragic backstory. [[spoiler: In the last chapter, after saving Izuku's life, All for One asks Izuku for that tragic backstory.]]

* In ''{{XOXO Droplets}}'', making a clique member your boyfriend gives you a perk such as instantly unlocking all date locations, having your energy refilled at the start of every week, and never losing Reputation points. There are also two "side boyfriend" options, Kam and Adrian, who will let you get items at the store they work at for free if you romance them. Ironically, the only romance options in the game that don't give you an in-game perk are the six ''main'' love interests because they're considered to be unfriendable jerks by everyone else.

* ''Anime/DigimonAdventure02'' provides a G-rated, non-romantic example: [[FusionDance jogress evolution]] triggers for the first time when the {{mons}}' human partners bond in such a way that "their hearts beat as one" and they gain a deeper mutual understanding: Daisuke gets through Ken's IneffectualLoner attitude by telling him YouAreNotAlone, Miyako [[LesYay delivers a]] GetAHoldOfYourselfMan to Hikari, and Iori begins to understand why the forces of evil are Takeru's BerserkButton.

* In ''VideoGame/SakuraWars'', the more one of the girls likes the hero, the higher her stat bonuses. In addition, a high enough trust rating will unlock special attacks.
** These include giant mecha that transforms from a theater.
** And a hot springs bath that makes mecha explode.

* Subverted in ''Webcomic/EightBitTheater'', where Black Mage's Hadoken (sic) is powered by love. That is, the divorce rate increases every time he uses it. Shame it never actually ''hits'', though.

* As the Valkyries in ''Manga/ValXLove'' are supported by the PowerOfLove, they level up through "Val Love" events, like holding hands to go to the store, studying together, eating a bento the Valkyrie made, [[TheLastOfTheseIsNotLikeTheOthers feeling up the Valkyrie's chest for half a minute...]]

* In ''VideoGame/{{Xenoblade}}'', raising the affinity between your party members allows them to equip each other's skills, increases the effectiveness of chain attacks in combat, and makes it easier to craft high quality gems.

* In the ''Literature/ApprenticeAdept'' series, werewolves only achieve adult status within the pack (conveyed by a [[MeaningfulRename fourth syllable in their name]]) after a ritual First Mating. When a female wolf comes into her first heat, she chooses a male for her first partner (usually an [[TrueCompanions oath friend]], as it's taboo for become Mates later). There's no chance of pregnancy at that time and it's considered good experience for both. Traditionally, each wolf takes the first syllable of their partner's name as their last. With the fourth syllable, they are considered full, adult Pack Members. We are shown, via {{flashback}}, one female wolf who is locked into juvenile status because of her refusal to mate... With a male. [[note]]The flashback is courtesy her [[BuryYourGays former]] lover, the Brown Adept[[/note]]

* In ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' getting married has a number of benefits.
** Your spouse will open up a shop to keep themselves occupied while you're away, and you get a cut of the profits (approximately 100 gold per every 24 hours). You can also buy and sell items from your spouse as you would a regular merchant.
** Once per day your spouse can prepare a homemade meal for you that increases the rate of health, magicka, and stamina regeneration.
** Sleeping in the same house as your spouse gives you a temporary buff called "Lover's Comfort" that increases the rate of skill-learning by 15% for eight hours.

* ''Creator/AnitaBlake'' books are a literature example. In Anitaverse, a triumvirate of a vampire, a lycanthrope, and a necromancer gathers a ''big'' power boost over the sum of their individual powers. The catch is, to gain the boost, all three have to be very fond of each other. A triumvirate doesn't have to be ''menage a trois'' (although, it implied, it often is), theoretically the triumvirs could just be very close friends.

* In ''XOXO Droplets'', making a clique member your boyfriend gives you a perk such as instantly unlocking all date locations, having your energy refilled at the start of every week, and never losing Reputation points. There are also two "side boyfriend" options, Kam and Adrian, who will let you get items at the store they work at for free if you romance them. Ironically, the only romance options in the game that don't give you an in-game perk are the six ''main'' love interests because they're considered to be unfriendable jerks by everyone else.
