No Capcom is a dealbreaker. I was thinking that I'd be even more excited for a proper Capcom 3v3 fighter that pulls from all their history, with no Marvel altogether. If this is just a bunch of Marvel characters, half of whom I don't care about, and no X-Men? Nah, I'll just play UvMC3 instead and play Injustice 2 (a totally different game, I know) for my superhero fix.
Actually, this game is sounding worse and worse. I can deal with 2v2 + assists, but there is a reason that I play 2 and 3 all the time, but I only pop in the original MvC occasionally. But a game where Marvel fighters overshadow Capcom fighters? A game with no Capcom fighters? A game with no Capcom fighters OR X-Men? Pure shite.
In that case, just give me a UvMC3 port to PS4 so I can buy that game a third time, and I'm good.
