i will look at alot of games and say, cause of their nature, they would do ALOT better on other systems than nintendo! such as splinter cell or red faction 2! hell, if wolfenstein came out for gamecube, it probibly wouldnt do well b/c gamecube owners are different and we have a different mind set than other gamers!
sonic is one game that i think would do much better on gamecube than the others! i feel that it will sell pretty good for ps2, wont do too well for xbox, but gamecube owners will flock to this game!
