The original Street Fighter 2 (no 'Super', 'Turbo', 'Championship', or whatever) was pretty much the launchpad of the Street Fighter series proper. It was pretty basic, you have your eight characters, each person picks one, and then you fight it out to determine who's the best button-masher.
And, just like in real life, both people couldn't pick the same character to fight in the same battle... even though this was available in the 'Championship Edition' of the game that was making the rounds in the arcades.
But what if, after seeing the Capcom logo fade in and before it fades out, you take controller one and hit Down, R, Up, L, Y, B? Do you hear a funny sound? You do?! Great!
Now, when both people try to pick the same character, they're able to, and whoever picks second gets snazzy new clothes.
Who says fighters can't be fashionable?
