It is the event where the demo version of Super Smash Bros. Brawl was playable at this event. This was the first tile Brawl was playable to the public. The 15 playable characters during the first E for All were Samus, Sonic, Pit, Donkey Kong, Meta Knight, Mario, Link, Fox, Pikachu, Diddy Kong, Ike, Peach, Zero Suit Samus (through Samus' Final Smash), Yoshi, and Bowser. The Random selection appeared as a starting option and featured a ? sign. This demo revealed many things that had been only briefly touched upon (or not yet announced at all) by the Smash Bros DOJO!!, including Sonic, Meta Knight, Peach, Ike's Great Aether, Norfair, and several items. The community's findings from the event were immortalized by in one of SmashBoards' biggest threads.
