Guessing you mean something like Heroes Harem Guild that used
Koikatu! It's the most anime like, all the games made using Koikatu! are being catalogued
here. Guess I'd recommend
Corrupted Kingdoms, for mainly Pixie reasons...
There's also games like The Inn that use
Honey Select. Don't think anyones making a list for it, but
Harem Hotel and for the girls not really the story
Mythic Manor.
