The Official Super Smash Bros. Brawl Project (Now at Phase 2!)

Oh! If you guys are serious about making sure everything's to scale, you may want to use BrawlBox to view the Attributes for each character (located in Fit<char>.pac, where the hitbox data is). If you scroll down to 'Unk27' (just under Weight), this shows the scale of the character when actually in the game.

It also shows why if you just import, for example, Mario and Yellow Alloy, they'll be the same size when that's clearly not the case on-screen.
