The first one was great if a little content light but I accidentally scratched the disc by moving the 360 while it was starting up :( It's kinda pointless getting another copy now as the sequel is looking superior in everyway :) Bring on November I say!
... so hopefully this one is a bit better and more fun, gameplay-wise.
I really wish Sega would just make a new F-Zero though. F-ZeroGX for the Cube is still a brilliant game.
