I guess any Capcom fighting game needs Chun-Li in its roster, but I can't think of anything interesting to say about how she appears, or how she works or sounds. Capcom games, and in part because many of them are uninspired, both in art style and design. This is in part because we've seen loads of them before in previous Marvel vs.
There are 30 characters - 30! - but so many fail to set the pulse racing. I put this deflation down to Infinite's roster of characters.
