A lot of games have bloated size not because of the amount of content in the game but because of inefficient piecework programming where things are a patched together Frankenstein monster. And when I say that I don't mean just porn games but include big popular games as well that have like a hundred different pieces doing their own bits of coding.oooohhh they dropped an update for this?! Last version I played was like .98, wonder what new stuff is in now...
*Edit* Wait a second - .098 was ~4.9gb, this .10 is ~2.9gb what is going on did they REMOVE content? Or lower resolution of scenes or something?
I don't know the case here, but I do know that the game itself had to be recoded quite a bit in this last update, so maybe at least part of it is cleaning up old bad code.
