I think they could've added a LOT more people in Brawl. Here's who I think should've gotten in:
Mewtwo
Dr. Mario
Roy
Young Link
Pichu
Lanky Kong
Tiny Kong
Chunky Kong
King K. Rool
Birdo
Wart
Waluigi
King Boo
Paper Mario
Geno
Mallow
Fawful
Knuckles
Tails
Amy
Dr. Eggman
Liquid
Pac-Man
Megaman
Zero
Viewtiful Joe
Skull Kid
Toon Zelda
Mii's
I have some great ideas, moves, and taunts for each of these characters! Maybe if they make a forth SSB, they'll add some, maybe ALL, of these characters! If you think I skipped some characters, tell me! They have to have a large variety of movesets, be from Nintendo(or other companies if the character is popular enough), and be in a video game. If you saw them in an anime, then no. And please, try to refrain from characters that won't make sense to the game.

No Cloud.
No Master Cheif.
Too many fan boys, and the fact that they would be too over powered.
And the only reason you added Dr. Eggman was for his final smash, the PINGAS blast.

Fine. But we need Dr. Eggman. There's Bowser(Mario), Ganondorf(LoZ), King Dedede(Kirby), and Mewtwo(Pokémon). We need something for Sonic. Oh, and Snake. Liquid, perhaps?
