I gave it an 8/10. It's a great game, but for me, its a bit slow paced with lack of combos. The game's only been out for 3-4 weeks so I'm placing my bets it will become better when people start to find out how deep the game can go. But for now, 8/10 is good enough for me.
I'm thinking 9.5/10 because it's a great game and the characters are very balanced for the most parts. I prefer this SSB over any other because of the things you can do and for all the crazy items that can turn the table. I think most people are rating it a 8/10 is because of the combos and such but you gotta remember that SSB series isn't your regular fighting game, it's in its own category completely just like Mario Kart for SNES was something completely new to the racing genre.
That's what i was thinking. it's boring if don't have someone to play with all the time.
Also it doesn't really use wii's "unique" things anyhow. Would be so much better on ps3 or xbox360. Better online, controller, graphics you got the drill.
