Brawl > Halo 3
Graphics: 10/10
I was in absolute awe at the graphics right from the intro movie.
These are the best graphics for any game on the Wii. Everything just looks so real and alive. All the character models are absolutely fantastic. Even Diddy's Peanut Guns look real.
Sound: 10/10
The sound in Brawl is impeccable. All the sound effects fit perfectly with whatever they're being applied too. The music is fantastic, and plentiful no doubt. With 304 songs you won't run out of tunes during a fight in this game.
Controls: 10/10
I haven't tried the controls for the Wii Remote and Nunchuck yet. But I can say that the Gamecube controls are just like Melee's, great. If you've played Melee then you should have no trouble using the GC Controller with Brawl. In fact, that's the controller I recommend you use. All the characters respond instantly and wonderfully with the controller. No slipping and sliding everywhere, no accidental moves.
Now, onto the one thing that keeps me from giving this game a perfect 10...... Oh, this isn't good. I actually can't remember what that thing was. I'm not joking, it was the only fault with the game, and it was so minor that I forgot what it was. Looks like this game IS perfect after all.
