Yes, and they also both use Katanas, and also have appeal to the Mature audience. not a Deocnfirm, but just a guess that we'd probably not have both Ryu and Scorpion
and I Understand that Ninja Gaiden got it's hype from the NES Games. But the First 2 Modern Ninja Gaiden Games also were popular, and that was in the era were Devil May Cry was starting it's heights as well
As someone that has played both DMC 1, 3, 4, and 5, I do understand that DMC and Ninja Gaiden are different games, but you can't tell me that those 2 franchises Don't get compared. I don't think they are as similiar as DMC and Bayonetta are, but there is Similarities.
Both Franchises (and Bayonetta) Appeal to the Mature Audience looking for some Slick action games. It does differ I will say that, but there is some crossover between the 2 I would say.
and No, Implementing Dante currently would be much Harder than Bayonetta ever was, unless they want to turn Dante into an Anime Swordsman and forgo all of his Sub-Weapons. even then, Balancing him would be much harder than Bayo or Ryu would
and look, I know it's not ideal, but if Dante can't be made to work into a Playable character for FP2, a Mii costume would have to suffice. This isn't me hating on Dante, because Dante would be the coolest character they could add personally that's not Shadow or Goku, but I think this is what might happen
