I'm not into fighting games myself, but a Switch port is a good idea.
Mortal Kombat 11 is a fairly good example of how it could be done, that was made for PS4/Xbone but brought over to Switch in pretty good shape while still being 60fps.
Nintendo and Switch owners get a quality fighter, MS gets some extra income, win-win.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023.
