I've always been a proponent of letting games go their natural way. If people love them, they'll keep playing them somewhere. And if not, you can't force people to play them. The thing I find interesting is that all the "let's play two games" people are dead silent now. Malik, Claude, and all those guys who were preaching that we should absolutely play two games, are nowhere to be found right now on that issue
Should Injustice 2 be the next game, however, I guarantee those people will be right back at it and extremely vocal about playing two games.
Now, that's a bit of a friendly blow-up (still love you Malik), but I think it's best that games run their natural course. Just like MK, when Injustice gets a sequel down the road it'll be back in force, on next generation systems, and I'm sure the excitement will be back all over again.
