Back then, I was playing, Super Smash Bros. Melee., Pokemon Leaf Green, Super Mario Sunshine, Mario Kart: Double Dash!!, NBA Live 2003, All-Star Baseball 2002, Sonic Advance 3, Sonic Heroes, Sonic Adventure 2: Battle. I was pretty much all over my GameCube at that time.
Such a good system!

Besides Resident Evil 4.. Call of Duty 2.. That multiplayer.. Also Shadow the Hedgehog and since then I lost all hope for any future Sonic game..
