By "girly" games I mean : games that have a soft/pink color scheme. About slice of life (preferably with romance elements), and non-violent with no/minimal combat.
I've already played Stardew Valley, Minecraft and Animal Crossing.
I will warn you that the platforming can be challenging, but if it's too stressful Celeste offers almost unparalleled accessibility options that will allow you fine control over the difficulty so no matter your skill level you'll be able to progress.
Great story, cozy atmosphere but still emotional impact, and the only "fighting" you do is against yourself.
My wife loves Stardew Valley and Animal Crossing, and she's been way into Hello Kitty: Island Adventure lately. It seems to split the difference between those things and add some of its own spice on top.
Unpacking, it's a relaxing puzzle game with some great environmental storytelling. Gameplay amounts to unpacking after various times moving house throughout a woman's life. It's really interesting to see how the different stages of her life are shown by the different living situations she moves into.
I've heard a lot of good things about VA-11 Hall-A. Haven't played it myself, but it looks like you play as a bartender in a cyberpunk-esque world and talk to the partons in your bar to get to know what's going on in both the world and their personal lives
Oh I think I know a good one! Haven, and it's currently 60% off. You play as a couple who escaped a controlling society to a foreign planet. (Three gender combinations can be chosen for the couple)
There is a combat element, and I don't think you can avoid it, but what you do is essentially clean the corruption off the local wildlife, instead of killing. Don't know if that works for you, but it's worth giving it a look I think.
Undertale, mercy run. The goal is to never kill a monster. It has combat, but the combat mechanic is moving your "heart" to dodge attacks and keep chosing mercy.
Wandersong! You play as a Bard who has to save the world through music and singing. Minimal combat and absolutely wonderful storyline that will make you cry tears of joy.
A bit of a wilder rec would be Cassette Beasts, which is basically Pokémon but better and has really nice optional romances. Very combat focused tho.
!infinitynikki@discuss.tchncs.de is an open world dressup game very marketed at women and has that soft pink color scheme, warning for being a F2P gacha game although you can progress without ever spending money. I usually avoid gacha but gameplay is legitimately good and "good gameplay," "high budget," and "for women" is a combination this game hits that I do not see too often in video games. (Other commenter is right there is a lot of girly shovelware.) There is combat, but it's definitely not the main focus. Very soft and pink. You might also like Beglitched (DEFINITELY pink and soft), and Style Savvy for Nintendo DS. I have been meaning to play both of those so I can't offer perspective on if they fill the romance ask, though Beglitched has combat. You might also enjoy Slime Rancher, also lots of pink and soft. Although it's also not combat-free it's not the main point either. Cattails was fun, kind of like Stardew but with cats instead, although as with Stardew combat does exist (though if I recall correctly it's optional and not the main focus).
Now probably my recommendation least like what you are asking for: I love the Touhou Project series. Don't let the male-dominated fandom and the tons of sexualized art of the characters fool you, the games don't sexualize the characters at all—I would feel very comfortable showing them to a 5 year old or Grandma. It is basically a bunch of superpowered women from Japanese mythology/folklore shooting very pretty lasers at each other. The focus is actually combat here, but I figured I'd give it a mention. Not specifically aimed at women but it's not not aimed at us either. Lovely music too.
My wife is in love with Disney Dreamlight Valley! It’s like animal crossing but with Disney characters and in full 3D. She dresses her character up differently every few weeks. She looked like a reindeer for December/January, and it was so cute! They’re very heavy on the fairy/cozy decor aspect, and while the expansions are paid, they do have free updates every 3-4 months.
She also recommended Calico, which is an indie cat cafe sim at heart, but you also get to dress like a magical girl, design your home, ride around town on animals like giant foxes, dogs, red pandas, more cats, etc. Very cute and relaxing.
On Your Tail is a cute mystery game set in an idyllic Italian seaside town with beautiful storytelling and character development.
She seconds other comments encouraging Haven, pulls the heartstrings and relaxing with minimal combat.
There are also the HerInteractive Nancy Drew games, which are older but fun female-centered mysteries. She recommends Phantom of Venice and Last Train to Blue Moon Canyon.
Don’t know if this fits the bill for you or not but my partner occasionally falls into the clutches of the Sims on their laptop. They’ve customized their installation with lots of outfit + hairstyle mods and expansions, so you kinda get to make it your own
I'll add Spiritfarer. It's not "pink" per se, but it's a much more "happy feelings" game. It's about taking lost sould and ferrying them on your ship, talking to them about their lives and feelings, and you can give them hugs of course.
A game where you play Silvia, a potion crafter who has taken over her uncle's shop on an island full of adventurers. You get to meet many kinds of people, both adventurers and not, and have a chance at romancing pretty much all of them (at once, if you select the polyamory mode). The art style is adorable (please physically release the cards, devs) and the voice acting is so well done.
Monster Prom
Strictly a slice of life / dating sim about trying to get a date for prom. The cast of characters are very cute, as is the art style. It's also multiplayer if you're into that.
Emily is Away
I believe this one is free. It's a nostalgia blast for those of us who grew up with instant messaging like MSN or AIM. It's been a while since I played, but I remember it being cute and very interesting.
Hello Kitty Island Adventure is similar to a very relaxed cross between Animal Crossing and Breath of the Wild. There are elements that depend on time passing in the real world such as socializing, holidays, and getting certain resources, and there are also a lot of very funny and cute storylines featuring all the Sanrio characters. You don't need to be initiated into them to have a nice time (I sure wasn't).
There's no combat, but there are many other systems and areas to unlock that make the game feel deeper than it originally looks.
It also has multiplayer, if that's something you'd use!
I played one a few months back that might fit the bill. 'Garden Life: a Cozy Simulator' It's a game where you grow/decorate a garden of flowers and sell/give them to people. Very pleasant.
Throwing in a recommendation for Tiny Glade. Not so much a game as a sandbox where you make small cottages, towns, or castles. Lots of options in photo mode for showing off your creations.
A recent one is Wanderstop, loved the vibes on that one. If you want to read more I wrote up some demo impressions here: https://lemmy.world/post/26452334
Not really "pink", and lacks romance, but very pleasant: Dave the Diver. Cozy-ish game with nifty characters. Only thing would be I don't know if you meant "no/minimal combat" because you don't want the mechanics or the vibes. Dave has not particularly challenging combat mechanics, and paw patrol levels of violence levels (although you are catching and eating fish).
If you like park builders, Zoo Tycoon is cozy as hell. Beware the DLC trap though. You can get the base game with a lot of meat pretty cheap, but the DLCs are like $10+ each and not really a good value IMO. But the game has a great vibe with some really neat mechanics that try and imitate real conservation efforts.
What would check the boxes through a "Hot Topic" lens is Promise Mascot Agency. Surprisingly wholesome, completely off the wall, combat is all card/deck builder based... I... it's a hard one to describe.
Doughnut county checks all the boxes but is rather short. Katamari if you haven't done it.
I hear good things about, but have not played: Naiad, Tempopo.
Weird recommends would be My time at Portia/Sandrock. They absolutely have combat, but have romance systems and a cuter aesthetic. Even the enemies are derpy/cute.
I really like the Style Savvy games on Nintendo. I started late with the one on 3DS but planning to get the Switch one eventually. They're nice and comfy games and since it sounds like you may already have a Nintendo, could be an option.
You could try Animal Well. Dark yet pastel-oriented colorschemes. Minimal "combat" but more of a puzzle and exploration style of gameplay. More mysterious than scary. Mild peril. Not romantic in the slightest, but very original.
I feel like Lost Records: Bloom & Rage that came out recently might be a candidate? I haven't played it myself because I don't think I'm the target audience but it seems like sort of what you're looking for?
I don't know if you'd consider visual novels a game, but even if the 'character' you're playing is a male, the feminine aspects come out really well in Doki Doki Literature Club.
Flock is an underplayed cozy game with no combat. You are a bird and you find other birds, sometimes not birds, to join your flock and fly around. It's completely chill and enjoys a really soft color palette (pink for sure but also purples, pale orange skies, blues, etc.)
Uhhh can give a game with no combat, but it doesn't have the rest. Well, female player character helps too, right? Heaven's Vault is a game about Aliyah and her traveling the rivers of the universe and finding artifacts or writing written in ancient and translating it. I like it, some prime find parts very janky. Can't die, I've tried in the few areas she can take damage.
I'm currently playing Research Story, that one is pretty cute. There are romances. I don't know about combat since I haven't gotten that far (just a few hours of play); it doesn't really seem like there will be combat, but there could be.
I'd also recommend Apico, Mudborne, Littlewood, or Fields of Mistria. I'm sure I'm missing a ton. I think Steam has "Cute," "Romance," and "Slice of Life" tags if you wanted to browse those on the storefront.
If you’re open to the idea of ditching a Microsoft product, I’d suggest Vintage Story as a Minecraft alternative that I think has a nicer aesthetic. It’s meant to be a sort of slow, “grindy” game, but if you sort of rewire your thinking to it being a slice of life game, akin to Stardew, I think it’s very fun. Fair warning the early game can be very punishing if you’re brand new to it, so explore the world and difficulty setting when you make your first save.
Somewhat cozy game with a femme lead I’m excited for is Cairn. It’s got a demo at the moment, but I’m very much looking forward to the full game. It’s technically a survival game about rock climbing, but if I had to guess the story will center the main character going through a lot of personal growth while attempting to scale a mountain (a la Celeste, also a great game) and overcoming a lot of adversity to regain some self confidence.
My time at Portia and my time at Sand Rock are pretty chill. They're kind of like Stardew but 3d, and I liked them more. It has some fighting but it's very PG cartoon-ish. It has a major mechanic where you just hang out with the NPCs, or go on dates with them. The second game, sand rock, is better but they're both good: https://store.steampowered.com/app/1084600/My_Time_at_Sandrock/
While there are combat aspects of it, you can play the fuck out of Stardew valley without ever even seeing the cave. Definitely slice of life, with open relationship options(open as in mf, mm, ff, makes no difference. Not screwing everyone).
