I can understand that, as I'd like to see the same thing, but I understand that for this type of game, it's really not a practical use of time. Most folks would probably assume that you just change the breasts and everything else conforms, not realising the work involved in a seemingly simple thing.
So many combinations of artwork, and that would get worse as time goes on. You'd need a guy that was just rendering the images for you as a permanent job, so you could get on with coding, and fixing bugs lol.
On another topic, which I might as well include in this post instead of creating another - I noticed it's extremely easy to become a prostitute, but almost impossible to become a slut, due to the frequency of rape and prostitution events. I felt it should be easier to be a slut than a prostitute, and maybe even be that slut could be a precursor to prostitute. I've been playing with the calculation a little, and currently have the slut count set to 20, (think it was 40), and simply subtract the (rape + sold) count from the total without multiplication, which brings the two closer together in terms of difficulty.
I understand for now its repeatable due to not being a lot of content currently, but It would be nice if Haven became just another location the player could visit, once it's completed, without it resetting. Of course, the outcome of that event was one of the extreme ends, like fire, that would block it off, and possibly create some events in the outside world. The area is only half done right now, so we don't yet know what's going to happen with the rest.
