Teatime (kaput) and Real (only does chikan and redo them alot). Illusion is probalby the biggest 3D maker out there. Tried Getchu with 3D search filter on ?
How about 3D Custom Girl Evolution? I never play the game myself but it looks pretty good from a youtube video that i saw, open world with custom girls
Kiss normally does 2D stuff but they have recently broken into the 3D scene with 3D Custom Maid (Well that was a few years ago) and soon they are releasing 3D Custom Maid 2. They also did an online MMO version but I dunno if it's any good or not.
