Some of the features of the game turned out to be underwhelming, but in the end, it really doesn't matter. In 1999, Smash Bros was a budget title that achieved greatness because people got to gather around and play as their favorite Nintendo characters. Melee improved the concept greatly with 2001, and while Brawl isn't as huge of a improvement to Melee as Melee was to the original, it's still bigger and better than ever.
Way more characters, way more stages, way more stuff to try out, and now with way more people to play against, Super Smash Bros Brawl is way more better than Melee, and will be played the hell out for many years to come. 9.6/10
