lol @ everyone jumping in this thread over just reading the title.
Yeah, i understand what you are trying to say, but the truth of the matter is when a game has just a few characters, it is easier to balance it out, since you can test each combination of match-ups against each other to the fullest extent without wasting too much time. The more characters you have, the more complicated it gets and it's not time/money efficient to test all that out. Brawl is gonna have a lot of character (more then melee that's for sure) and some characters will have a bigger advantage over others. It happens.
Now most people say this would create a tier list. I would say take the character on the bottom of the list, match it up against the guy on the top, and you have your first counterpick, which inevitably, creates tiers.
If nintendo could make a balanced game, as impossible as that would be, every other fighting game would get dropped and Smash would become a religion, lol.
