Games exclusively for Nintendo Gamecube

[Kitsune Sniper]

Bust-a-Move 3000

I don't think this was a Gamecube exclusive. The US version is the same game as Super Bust-A-Move on the PS2, except for some changed backgrounds (according to Wikipedia and the back cover art of both games, anyway).

The Japanese GC version, however, had a four player mode.

Edit: Oh goddamn this is a thread from 2004? Agh!
