This new Kirby game is something i will be looking forward to. I have Kirby Air Ride, but did not enjoy it as much as Kirby's Adventure, Kirby Superstar, or even Kirby Tilt'N Tumble. On second thought, I did like Kirby Air Ride better than Kirby Tilt'N Tumble. The concept of that game was interesting but i found it very frustrating rotating the game boy color around to move Kirby.
But, back to talking about the new Kirby gamecube game. Perhaps a smash brothers style mulitplayer mode in this game would be interesting. Or, as D-Mac said, a co-op mulitplayer mode set up in the same way as Kirby Superstar would really make this game great.
