I have an idea that soul calibur can crossover with UFC and be sucessful.i think soulcalibur can crossover with UFC (but their will be two versions like tekkkenx streetfighter and Streetfighterxtekken)meaning the sc version will be more weapon based fighting and have character creation options etc. and The UFC version will of course be more undisputed but has realistic violence and has a weapon switching system and etc.The version will be called soulcaliburxUFC(soulcalibur version)and UFCtxsoulcalibur(UFCt version).And P.s.UFC characters have used weapons before.Look up UFC deception,UFC Deadly alliance ,UFC Shaolin monks and UFC Armaggeddon.And as a plus UFC and Soul calibur are both Popular games.
