other than better graphics and a demo of REUC, no.
and the wii remote makes aiming much easier. items that appear from defeated enemies appear instead of just the glowing colorful light......
and the biggest difference is that El Gigante takes only 2 stuns, since wagging your wiimote is easier than pressing buttons.
okay the i had the ps2 and gc versions of the game i mean since i had it on gc first i felt it controlled better on the gc but the ps2 with the extra stuff but the graphics looked like exactly the same so guys stop bitching about how the gc version of the game looked so much better then the ps2version so guys if u havent played both then just dont complain
