/hgg/ Recommends you check out these games if you have not done so already!
ILLUSION
Makers of Artificial Academy and Artificial Girl 3, but probably best-known for the controversial Rapelay.
They have no idea what they're doing anymore and every new game is a disappointment.

Other games: Hako, @Homemate, Rapelay, Biko, Battle Raper
TEATIME/FULLTIME
Makers of the Love Death series, among others. As of 2013, they closed shop and were folded into Illusion.
Many of these games suffer from fairly major performance issues! Expect long load times and poor framerates.
