Now I don't know about you, but I truly LOVE the first one. It's one of the best games of last generation, IMO. I didn't play Park Patrol as it seems to much of a spin off (I might be wrong), but this one looks much closer to the original installment.
I would prefer it on the Wii, but I'm sure this will be a first day purchase for me.
BTW, Skip, if you read this... put some pressure on Nintendo to bring us Captain Rainbow ;)
