Classic mode is virtually the same as it was on the very first Smash Brothers for Nintendo 64. They know they had a good thing going and kept it right how it should be. You are matched up against randomly selected enemies on each stage, and will have to fight them in a normal Vs. Mode style Brawl. It's probably the simplest mode of the game, but it's still a lot of fun. It's the perfect way to train and build up your skill against varying foes while earning items and unlocking secrets.
Every man dies, but few truly live. Live your life to its fullest, every day as if it were your last.
