I played the PC demo many moons ago and I think this could be a perfect fit for the Arcade. My only hangup is that I've read that they pulled out most of the races for add-on packs.
ugh. MT looks neat but I'll wait to see if they decide to charge for those before I buy it.
Well, from the press release:
For about half the price of the full game, players will be able to add additional races and mini-games to "Mad Tracks" by downloading the Bravo and/or Encore expansion packs. Each expansion pack includes an additional 15 nail-biting races and action-filled mini games for 350 Microsoft Points each, extending the fun and offering a great value.
