Well last night I finished all the grand prix levels in Mario Cart with Gold. That unlocks all of the riders, all of the tracks, and all fo the carts. I can now race with any driver, in any cart, on any track. I went back and re-raced the 50cc races and can’t believe how easy they were now. I’ve now moved on teh playing the “Mission” levels and for fun the battle levels. This game is way to much fun.
