Well, lately I've noticed so many posts stating ideas which originated from other games, or at least similar to them (psi ops, projectile reversals, etc..) I figured it'd be rather convenient to just make one thread strictly for nothing but that. To post features from other games that you would love to see incorporated into MK: Deception.
Me personally as many have already pointed out before, I'd pick a single player versus mode. It'd be so nice not having to play on arcade every time you want a quick match.
