This is probably just me but I would ignore most sports recommendations in this thread. Playing SSX on anything but a Dualshock is just fool's gold. I'll never forget when my friend bought Tricky because we were having so much fun with it at my house, but all he had was a Gamecube. It took him about a week to take it back.

Mario. Golf.

I have no care for either golf or Mario sports games but I still play that game every now and then to this day.

You got RE:Remake for the gamecube, nice choice it's an anwome game. Though I wish it was ported to ps4 or xbox one, but Nintendo owns it.

Both main LoZ games and I think Twilight Princess on gamecube was the better version.

Metroid Prime (especially the first)

Tales of Symphonia

MGS: Twin Snakes

Super monkey ball and paper mario not getting enough love.
