for me its tomie. such a great sandbox with so much opportunities and such great variety of scenarios.
sadly it was a racist caricature of korean people made by a japanese who lived in korea, and when they found out who he is, he went radio silent. may his soul rest in peace.
here's some more pics.
as you can see, this game singlehandedly redeemed 3D porn games.
