Besides that, I bought My Girlfriend is the President because of how ridiculous that trailer was, but only played it for an hour.
If that's not a recommendation, I don't know what is. When I think about it, I haven't actually played that many dating sims, besides Katawa Shoujo, which I liked, but it sounds like you weren't digging. I don't know how much of a dating sim it is beyond (I'm guessing) selecting which route you want to go down, but it is highly regarded.
Might be worth checking out but again the current fan translation patch only has a little bit of the game in English.Off the top of my head I'd also recommend Majikoi, which is currently only readable through a fan translation but will be released by JAST USA sometime in the future.There are many others but that's all I can think of at the moment.The only one I've played is Katawa Shoujo, it's free. The guy you play as kinda sucks but I could connect with it a bit 'cause the game is all about these ppl with disabilities.If you really like it, the game has plenty of replayability quality games that I liked a lot and that are free: emily is away and love is strange.For visual novels I really would recommend Katawa Shoujo, the "disability girls" game.
