The long-in-development Card Sagas Wars, a super-deformed fighting game based on the MUGEN engine, is a place where fighting game dreams come true. In this case, for those who have dreamed of seeing Master Chief take on Samus, Raving Rabbids and...Tingle?
MUGEN is a free 2D fighting game engine (and originally a customisable 2D fighting game) that lets users create whatever kind of fighting game they want. Normally, they create fanboy fantasies like the one above. As you would.
