SSBB is an instant classic that should have you playing for a while. A long while.
No real records are kept in online, as in how many you're played, how many you're won, etc. But it's still a great and very exciting game. The visuals are one of the best to come to the wii. Very smooth frame-rate regardless of all the action going on. Controls are easy to set up and use.
All in all the game is very exciting, and although there aren't really a whole lot of moves to take out, it's still amazing to watch, and because of that, it doesn't really get boring. Not quickly anyway.
There are a whoooole lotta things to do and keep track of in this game. Like no other SSB. If you enjoy faced paced fighting games, you seriously need to pick up this game...asap.
Btw it will most likely take you a while to pick a character which you are totally comfortable with and learn with quickly. Mine is Meta-Knight =D
