I dont think there's much for GC thats great to play that exclusive but there are some nice redo's and ports for it and even a few exclusives.
Metriod Prime is good
Skies of Arcadia Legends( yes it was for dc but this version has a new character and improves on the exp and battles per step ratio. This is defanitly the better version to play just for the more exp per battle.)
Sonic Adventure DX ( Better menus and models than the Dc version)
Metal Gear Solid: Twin Snakes
Its just a nice face lift and the MGS2 engine on the first game.
Thats about all i've really cared for on GC to tell yah the truth. Just not my type of selection I guess
