Best GameCube Game Other Than Super Smash Bros., Zelda, or Metroid

[h2ohno]

For me, Rogue Leader is the best game of the whole 6th Generation, let alone best on Gamecube or best aside from Smash and Zelda.  Any game from the 6th gen that rivals it for me is because of the addition of motion/pointer controls in Wii ports elevating the experience like Prime 1 and RE4.  On the Cube those games are far below RL for me.
