I played it at a friend's. Wow. The whole final smash thing is cool, and scary too. SOme of them are just funny (like King DeeDeeDee's), and some are awe-inspiring (like Samus'). Very good game.
Guess it's the availability of the game. So much copies had been made and so much had been sold in a certain part of the US. Nintendo sure has to reproduce more copies to sell in the other part of the US.
SSBB is released in Europe in May, unfortunately... So it will take a while until it's available in my place.
