its not really the violence itself, hell DOOM exists. its more so who the target of the violence is. beyond steam there are laws that prohibit the depiction of violence against children (again, even if the disclaimer claims that all characters are above 18, anyone with a set of eyes and a couple of brain cells know this isnt true in the context of the game or how Lona is presented). Valve has taken heat for this kind of game before, and while they've found a decent middle ground for hentai game, they wouldn't be dumb enough to bat for this game and I wouldnt blame them, not when it would land them in actual hot water with the law. Ever wonder why you cant kill snot nose brats in skyrim, or why GTA has no children in it? Thats why.
