Sex Realm was one of the first H-games I discovered, somewhere around 2010. It was also the game which made me start actually learning English (what I was taught at school was pretty much useless), by trying to communicate at the game's then-alive dev blog. I was sad to see the project dying; it just started getting actual content.
P.S. For any Russian-speaking players out here, do not play translated version; it's my old shame which I never got the chance to fully fix before project died (plus, translation was going through excel table, with zero chance to test the changes until they getx implemented into game).
