Any good games I can play on my original Gamecube that are hard to find?

Hey fellow Redditors, I've been rummaging through my attic and found my old Gamecube that I haven't used in years. I'm itching to dust it off and get some gaming action going again. However, the problem is that most of my favorite childhood games are super rare or hard to find nowadays. Does anyone know if there's a particular Gamecube title that's notoriously difficult to track down? Maybe something like a limited edition release or a Japan-only title? I'm eager to dust off my old console and relive some nostalgic gaming memories. Any leads would be greatly appreciated!
