To be Honest. I think this game looks pretty cool.
I think if I eventually get a PS3 I'll get the Eye toy and this game - or one of the other card games that may get developed for it.
What would be cool is if they had 2 play modes: Standard card battling and a single player RPG - where you use the sixaxis to play the game, then go into battles and use the cards.
As it is though, I still think this game will go very well as it is something completely different and is the first of it's kind. People love to have the newest things and I think this will sell well, in both Japan and US, and even Europe maybe.
I for one would enjoy this game had I a PS3.
It's me... no really, it IS me!!!
