I know what Incest means...There are consequences and that's not what incest means. The word you are looking for is harem.
I didn't complain and I am not about to, not sure where you got that from. Also, I haven't finished the game yet, I was looking for a walkthrough and the Incest mod was the first thing that came up. Now that I am reading the mod description again, I guess I was wrong about what this mod does (probably because I didn't even bother reading the description), I thought it would allow harem between the sisters without having to break up with them (Cause I assume it's gonna backfire at the end).It doesn't and won't. Play how you like...but don't complain if you can't have any self-control and the world burns
(I have a save just to see that happen btw lol)
Also, my initial question was what's the difference between the game and the web version (it's full of bugs, is this version buggy too?), guess I wasn't clear about that.
