Ah, I didn't get you, I thought you were asking for some custom made mods for this game, but if I get it now correctly, you ask for more modifications on the look of the game itself compared to others.
Well, to each their own. In my opinion there is quite a decent amount of body variety in this game, but what matters more to me is setting and story. I haven't seen any of these characters before - similar, yes, unavoidable when using the same software (which by the way is not HS), but not as blatant as in other games - which I still enjoyed, because the stories were different, just like I can accept the same actor in different movies despite looking all the same. And there is more variety in this game, at least for me, than in your average "guy comes home to mommy and sisters landlady and roommates after years game, no matter the graphics.
However, as a point of notice, this isn't a porn game.
