I never had a Game Cube, as I went from my N64 to my Xbox and then Wii. But I have played on one at work for the past couple of weeks on my lunch breaks, and have not seen a fault with it yet. I have always been a massive Nintendo fan- with my faith in them wavering slightly in their consoles in the past couple of years, but their game design is always second to none.
So here is to you Game Cube! Bring me many more lunch breaks filled with Smash Brothers Melee!
