9.9
The game is full of amazingness.
I've spent months playing it with 3 of my classmates 2-3 times a week for couple of hours. Its also the only Wii game I have played every month now (from October last year, when I bought my Wii). I love the gameplay, soundtrack, characters and everytihing else there is(except online, which kinda sucks :P).
Its also one of my favorite games of this gen.
Did I mention I bought Wii just for this game? ;)
edit: Before that, I've played Melee for months with the 3 mentioned classmates. Ah, those were the days.
