I just recently bought a Gamecube and picked up Resident Evil Zero and Metroid Prime!! All I can say is AWESOME!!! My only worry though is with Metroid Prime since it is a used copy from EB and has some pressure marks on the CD. The game has worked smoothly so far without a hitch,-(I just picked up the morph bombs and saved) but is there any reason I should worry about error correction later on in the game? Thanks!
