MvC2, X-Men '97, etc. Disney giving the people what they want.
No joke, this is probably going to be my main fighting game until something better. I've tried SF6 and Tekken 8, but I can't get into these new games. MvC3 was probably the last fighting game I really dove in on.
I got really good with a highly annoying Spiral/Storm team in MvC2. It wasn't like an MSS, MSP or Duc's team, just two batteries playing keepaway with insane chip damage. Probably some of the most fun I had playing a fighting game.
