@Cyringohn:
It takes place during the midnight release of the game.
The biggest catch is that it's:
+Wiimote & Nunchuck only.
+Starting roster only.
News to me, though I was aware that you had to use whatever controller they provided. Doesn't bother me too much, since I was considering using that control scheme overall. If I play with the game cube controller, I'll completely have to unlearn Melee, whereas with Brawl I can use a new control scheme to start out fresh. It sucks that eventual tourneys I may or may not be going to probably won't allow such a controller (or classic controller) due to it being wireless.
Also of note, each match is a 1 minute time match, so either you get the kill and play keep away or it goes into sudden death where it either ends quickly or stalemates till a bomb kills your ass.
