I'm loving the look of this game!
I always found it a shame that turned into a 2d game instead of a 3d game. This looks like a lot of fun and Rachel looks very good, I think Chloe could do with some work but overall promising start.
Yeah the amount of games that have that kind of content behind a patch and carry on without any issues is very high. There's probably hundreds of developers that do exactly that. I agree with the above comment from Badjourasmix.
