Systems are indeed nice, as I support the game companies the best I can, and I don't buy even used consuls.
If you buy used consuls the money does not go to the video game industries.
But as far as Nintendo Game Cube goes, I still own the system, and the only game I truly liked with excellent replay value, was Super Smash bros. Melee. This game never got boring to my friends and I.
But I would like to see a good working game cube emulator, as I own a laptop with impressive specs

And it would be nice to have Super Smash Brothers melee on the go =D.
So hopefully we will see a good working game cube emulator soon enough, but in the mean time, Doomulation is right. There is no reason on why you can't support the game companies that offer us their material. GO BUY THE CONSUL (sorry for the caps).
