Gamecube actually had some decent games. Smash Bros. Melee = One of the funnest video games ever. Then there's the mario sports games that are always great (Tennis, Baseball, Soccer). The 007 games were good shooters for the time. Then there's the Metroid Games, Resident Evil 4, Zelda, Prince of Persia, Wave Race Blue Storm, Super Mario Sunshine, Animal Crossing, Spiderman 2, and some more. If you had that collection of games, and put the game on HD Component cables, it might be some pretty good fun for old times sake
Might as well hold onto it, or just take the 20 bucks store credit at a Gamestop.
