4 proved that they lack the mental capacity to make proper DMC game.
That statement proves absolutely nothing, except maybe that you don't understand the concept of proof.
Look, sorry if I sound harsh. I'm just trying to get proper answers that aren't based on how you specifically feel. What you feel is fine, but if that's based on some concept you dislike for no logical reason, or some reason you can't explain well then that can't hold as an argument.
You can say I disliked DMC4, and no one can hold that against you, but when you start saying that it was bad in general, concerning everyone, then you have to give reasons why this should hold. Those reasons should hold ground, not be based on how you feel regarding an issue. --- Beatings will continue until morale improves!
