Well, discussion of CONTROLS aside (which is kinda funny, when you consider the fact that most of the arguments laid forth don't even apply to me) Virtua Fighter 4 Evolution would be a good game to put on Gamecube, for the same reason that Skies of Arcadia Legends is so high in demand for the system... lack of palattable titles of that given genre. Seriously, until Soul Calibur 2, VF4E would have NO competition due to the fighting genre's weak showing for Gamecube... and if VF4E were put online for the Cube, that'd make it unrivalled even AFTER Soul Calibur 2 comes out... and it's not like they can't, Sega-AM2 already has online servers set up for VF4E, VF.net
So... I mean, seriously, with VF: Quest coming, I could see it hitting Gamecube, for sure...
