Well, I have never played the game and like I said it just stuck out in my mind (hard to forget a commercial with a beloved childhood character flying around on a waterpack). I thought since the commercial showed basically nothing EXCEPT him on that pack, that it was a bigger part of the gameplay. A bit like taking a sample if you will.
I have played Gamecube a few times before and didn't care for it much but if you'd like to try to convince me to give it a second try, I'll keep an open mind. Hell, you may even turn a few other members into Gamecube fans while you're at it.
