IGN review of SSBB is...

[The Ghost of RubangB]

9.0	Presentation An impressive lineup of stages and characters, including some from third parties. Amazing soundtrack. Gorgeous cut-scenes. Simple menus. Long front-load and lacking online options.
8.5	Graphics Looks like an enhanced version of Melee. Improved character models and backgrounds. Everything runs in 480p, 16:9 and at 60 frames. Even so, the graphics definitely lack detail in areas.
10	Sound One of the best soundtracks ever created. Sound effects, meanwhile, are perfectly punchy and well-suited to the characters and environments.
9.5	Gameplay Tight control, more balanced character move sets, new final smashes and more. We're not particularly fond of the single-player mode, but multiplayer is so good we just don't care.
10	Lasting Appeal Destined to be played for years thanks to spectacular offline and online multiplayer modes. One of the great four-player games of all time.
9.5 Incredible	OVERALL (out of 10 / not an average)
