I finished Need for Speed: Underground on my Gamecube today. Woohoo! It was fairly easy, there were just a couple tracks that drove me nuts. Like track #85. And the low-rez graphics made the game a lot harder than on the PC because you could hardly make out what was coming up to react in time. On the other hand, I liked using the GC controller much more than a joystick on the PC. Much easier to control. Now I need to pick up NFS:U2, it's cheap nowadays too.
