lol ^ interesting, WB calling M$$ and Rare? hmmm
I'm sure money wise either would be a major hit sales wise/profit wise MK vs. SF or MK vs. KI?
But concerning the question, I kind of have two answers.
8 if Capcom is very openminded....it's not like they never made a bloody game, RE series, Dead Rising....but more so it will come down to "how much they love their characters" would they let Sub rip off Ryu's head? Fatalities are a key part of MK and what made MK....MK(not everything but a big part) so an MK without fatalities=BIGGER fail then MKDC in terms of violence. At least DC let them have finishing moves, watered down yes....so if DC can budge THAT Much at least then Capcom can IMO.
KI and Rare definitely would, no question...KI was inspired from SF and MK anyway....
P.S. why does it seem these days MK is the only fighter(much like back then in the golden age) that's willing to get their hands dirty? So you make the game rated "M" big fucking deal lol...some people assumed Marvel vs. MK would be all out...no it wouldn't either lol you think Stan Lee would approve Spider-Man's head being torn off by Sub-Zero? I think NOT
