emily is away is not gonna give you good feelings or anything, but it's really good.
love is strange probably only works if you've played life is strange.
Edit: Also, the Visual Novel Database is your friend if you are starting at ground zero and are looking for recommendations.
I appreciate that Umineko is good(I really liked the anime adaptation of Higurashi, though I've heard Umineko's anime is pretty bad), so I'll keep it in mind but it's not what I'm looking for right quality games that I liked a lot and that are free: emily is away and love is strange.I tried Katawa Shoujo already and didn't think it was all that.Like, it's basically fine, but nothing in there was particularly doing it for me either.Also, there isn't a full fan translation available for it yet, but I played a demo for Amagami a few years ago and it was pretty good.Might be worth checking out but again the current fan translation patch only has a little bit of the game in English.
Love is Strange kinda makes me laugh, I did play and like Life is Strange alright, but it's pretty funny that someone wrote a fanfic VN about just the girls going to the school, including the murder victim it seems. Steins; Gate might be cool, I loved the anime adaptation of that too.
