My car is now sorted, so I'm feeling a lot happier. :)
Yesterday I got a copy of Viewtiful Joe for the gamecube.
This is a seriously mad game. Highly retro in many ways (it's fundamentally a 2d platform game and beat-em-up), but cutting edge in innovative gameplay and odd graphics style. Well worth a look for people looking for something completely different. The only caveat is that it does have a few old-school irritations in that it is really quite hard, and you have to retry quite large sections if you die.
