The GameCube was secretly one of the most successful consoles Nintendo ever released based on software sold per hardware unit. I adored my GameCube and till this day remember the enjoyment of playing Metal Gear Solid Twin Snakes, F-Zero, Super Smash, Wind Waker, and a title which demanded a squeal but it never came to the surface which was Freedom Fighters and the Advanced Wars 3rd person perspective title.
Come to think of it I still have all those games... My 5 year old will be getting a GameCube for his birthday now.
