I used to think DMC would have been similar to castlevania or older ninja gaiden if it came back in the days of 2 dimensionality.
but stylistic combat is the thing DMC is known for, hell, it pretty much invented the genre. So castlevania's platforming or ninja gaiden's speedrunning wouldn't do justice. I think the game should resemble 2D fighting games as far as movesets go, otherwise it could follow old castlevania formula. As long as the emphasis is in the fighting enemies.
