Just picked up a gamecube, need suggestions!

Just bought a Gamecube for around $30 bucks and I need to know what games are good on it! Help me out please! :)

EDIT: I picked up SSBM, Super Mario Sunshine, Pikmin 1&2, Paper Mario, Timesplitters 2, Warioware, FFCC, Soul Calibur 2, and that's about it. Having a hard time finding Killer 7, Resident Evils, Wind Waker, and Luigi's Mansion. Any Help?
