I own a Gamecube. I recently decided to finish my collection and beat all the games I never got to. On this list include:

Super Mario Sunshine, Luigi's Mansion, Baten Kaitos and Eternal Wings as well as The Wind Waker.

I now own these and am working on beating them all and reviewing them (Luigi's Mansion is the only one done so far.)

Back in the day, I also completed such games a Pikmin, Pikmin 2, Animal Crossing, Paper Mario2 and a few others which are escaping me. Metroid included by the way.

So if anyone has any ideas for games I may have missed send me a private message and tell me why you liked the game. Thanks!
