This was supposed to be for @asususasa but in the middle of writing I thought this could be useful for someone else, so here's Tacky's general list of otome recs. It took me over an hour to write so I'm not proofreading it.
DS
Not much to say here because back in those days otome games didn't get localized. The stand outs are Tokimeki Memorial Girl's Side 1st Love Plus and Tokimeki Memorial Girl's Side 2nd Season, who have English fan translations. Slice of life games where you play as the protagonist through her three years of high school. And if you feel like a student-teacher romance that would make Sakura Kinomoto's mom proud, these are your games.
PSP
Still well into the no localizations era with one exception: Hakuouki Demon of the Fleeting Blossom. Not recommending it on PSP because there are better versions. Tokimeki Memorial Girl's Side 3rd Story Premium also has a fan translation and should be played over its DS counterpart because it has added functionalities. Sadly this time around the teacher is a secret character and a shota.
3DS
There's Hakuoki Memories of the Shinsengumi. Still not recommended because we can do better.
PS3
Hakuouki Stories of the Shinsengumi includes the original game and the fandisk with some neat animations added. This is the version to play if you want the original experience. If you want even more routes, go for another version.
Vita
Hakuoki Kyoto Winds and Edo Blossoms, Collar x Malice and Amnesia are the best games you can get for the Vita imo. Some people dig a lot the Psychedelica of the Ashen Hawk and Psychedelica of the Black Butterfly (I've only played BB, it was good but wasn't the bestwouldn't rate it as high as the others). There's Code Realize and its two fandisks (Future Blessings and Wintertide Miracles) and many people swear by them, but while I liked the common route in the first game, the rest didn't do it for me. You can find all of these except CxM and the CRs on Steam, and the Hakuoki games get dirst cheap on sale. Best bang for your buck of the saga. The CR games have PS4 ports and CxM has a Switch one, which you already know.
Switch
*rolls up sleeves* LET'S GO.
To get it out of the way: Hakuouki KW and EB are getting a Switch rerelease and a new translation and will be released as a single game, Hakuoki Chonicles of Wind and Blossom, on August 1st.
Collar x Malice fucking nails the mystery and lowkey horror vibes with and excellent plot that's interconnected in every route. CxM Unlimited is its fandisk and only recommended if you really have the CxM itch, because it's mostly fluff and the little plot there is is at most functional. It has a super interesting route where Ichika joins Adonis and you get to see its inner workings though. That was very interesting.
Bustafellows is 100% found family vibes with a very assertive protagonist. It's a mystery/action story and the team dynamics are sort of Ocean's 11-ish. Hilarious, heartbreaking at times, I've never felt more dread in a game than heading towards the basement in a certain's guy's route. There are two unlockable stories after you finish the routes of the guys, one of which I thought was glorious, another which sets up a sequel and is a big downer but I also really liked. It gets heavy at times with murder, suicide, sexual assault, human trafficking, among other kinds of violence, but despite it, it's generally a very funny and upbeat game. We're getting the sequel next year. Also available on PC.
Café Enchanté baits you with the premise of being a girl who manages a coffee shop patronized by handsome supernatural beings, so it's a real surprise when the cannibalism shows up. Anyway. Great game, but I'm afraid saying more would kind of defeat the point. Reminds me of Megami Tensei games, so if coffee shop AUs with supernatural world-ending threats are your thing, go for it. Just be warned that the fandom has kind of collectively agreed that poster boy's route never happened.
Birushana is a hidden gem that goes on sale super cheap and is also probably a hit or miss thing. You play as the legendary Yoshitsune, who in this game is a girl disguising her gender, but she's an amazing warrior as in history. It has the best otome couple I've ever seen, bar none, with Yoshitsune and Noritsune. The game is worth the price just to see them fall in love on the battlefield and watch Noritsune chug down Respect Women Juice all the way through it. The thing is... the rest of routes aren't great. Don't get me wrong, I enjoyed how utterly unhinged they got at times, but the plot got worse as it deepened. Still. Noritsune. And I loved that most of the guys respected her as a warrior and were aware she was as capable or a better warrior than them and she didn't need a man to protect her. Very refreshing. One of my faves got done dirty by the translation because they started pulling lines out of thin air to make him creepier. Just him. Why. It's not like he needed the help.
Virche Evermore Error Salvation is also a good one if you can handle continuous drama and see egregiously bad science and say, "You know what? It's magic. Humans in this world are just built different." The worldbuilding is really interesting and the characters very enjoyable, though they don't feature a lot in each other's routes or aren't that friendly with each other. The continuous tragedy may tire you out, or maybe it'll work and emotionally destroy you. It didn't get any emotional reaction out of me until a certain point near the end, but I enjoyed the game a lot, nevertheless. We're getting the sequel this November and I'm really looking forward to it.
Variable Barricade: a fun romp where a young heiress has to chose a fiancé among the four disaster bachelors her grandpa has selected. It's not really similar to Ouran, but it reminded me a little of it at times. It's a pretty light game. The BFF is a gothic lolita otaku who has the time of her life shipping you with the guys, and the butler... oh boy the butler.
Amnesia, as I mentioned earlier, has a PC port as well as the Vita version, as well as two localized fandisks for the Switch (Amnesia x Crowd) that I can't speak of because I haven't played them yet. The protagonist has supernatural amnesia and must piece together her life while avoiding that other people realize she's lost her memory. It's a super intriguing game the first time you play, really nailed the being completely and utterly lost in the protagonist's shoes. A required play to get in on the cage jokes. It's sort of a rite of passage for otome gamers.
Jack Jeanne has probably the best group dynamics of any otome I've seen. I think some people have issues with the protagonist because they find her passive, but to me she felt the complete opposite. Everybody is adorable. A sentimental story of hard work, being young and and fighting for your dreams, 10/10, no notes. I lied, there's a note: Tanakamigi deserved a route! Where is our Tanakamigi route! щ(゜ロ゜щ)
Last but not least at all, the two Piofiores. Mafia games where all trigger warnings you can think of apply. Well, maybe not the cannibalism, that's still Café Enchanté's crowning glory. Fated Memories, the first one, has its ups and downs, but has very enjoyable characters, rock-solid worldbuilding, an amazing atmosphere set in 1920s Italy with a jazzy soundtrack that ends up living rent free in your brain. The last routes of the first game, Gil's and Finale, are worth the full price of the game alone. Piofiore Episodio 1926 is a masterpiece of the otome genre. It doesn't have a single boring route, and the final stretch (Advent Calendar-Alternativa-Secret Character route) has the best writing I've seen in an otome. Lots of points of view and situations interconnecting, an excellent final couple, top notch interactions between the main characters. Just the best.
