...then it might work a little like this video by Chris Le. The footage isn't of an actual game, though, unlike the 2D League of Legends fighting game -- not that that makes it any less cool!
Obviously, you can see some Street Fighter influences in here, as well as Marvel vs Capcom. Neat.
The video is a part of a series -- Le hopes to release a new video every month.
