There are plenty of copycats these days including mortal kombat or whatever that is, the mouse game. I feel like its going to be saturated so much that eventually none of them will make any money at all. Thats the thing about this stuff, they end up with oversaturation very quickly after one good example, maybe a few more but that's it. I think we should not make these many copycats, but how are you going to tell people to stop making it? They are going to give their best chance, and probably going to end up failing but they are going to keep trying for a few more months at least, I am sure of it.
