Up and Coming Adult Video Game Studios
Up and Coming Adult Video Game Studios: Black Love Interactive and Nest Egg Studios
One of the great things about being involved in the IGDA SiG SIG is getting the scoop on new studios that are coming out with adult themed games.
From Black Love Studios comes Rapture Online, a multifaceted adult sex game. You'll be able to live out fantasies with both solo and multi-(real or otherwise)person situations, create new settings, and interact in a multitude of sex-positive games.
Nest Egg Studios (Warning:: Flash only, loud music) is working on Heavenly Bodies, a multi-genre spanning MMO game for adults. Unfortunatly, I don't have much more info than that, but it looks interesting. :)
