Every once in a while a game comes along that has so much hype behind it that it sort of becomes an event. A game that you see yourself justifiably taking time off work to play the first few days it is out. Shutting out the world so that you can fully immerse yourself in gaming excellence. For Sony, you have the Metal Gear Solid series. For Microsoft, you have the Halo series.
In Nintendo's case you have the Super Smash Bros. series of games. Fighting games which are so entry level to pick up and play, but never so easy that the game becomes repetitive and boring. This is the case for gamings' newest "event" Super Smash Bros. Brawl for the Nintendo Wii.
