M.U.G.E.N

MUGEN is perhaps a slightly odd fit, in that it is not so much a game creation tool, as it is a framework for created gighting game characters (and other assets). That's not to say that sometimes packages aren't released containing a setup of characters and stages, and treated as a game in its own right.
