My personal favorites:
The Visit
Monkey Business
Milf City(for what it is)
Sisterly Lust
The Fate of Irnia
Shelter
Flirty F
Where the Heart Is(originally)
Shut Up and Dance
Games the give the illusion of choice but the options don't really affect the game. Also when a multi route game has a main girl and less focus on the others and doesn't advertise that.
I personally don't like forced harem games, especially those that make it seem like its giving you options. I don't want to
have sex with a character I really don't like. But that's just me.
