Spectator Mode was announced today on the Smash Bros Brawl website today. There are multiple games out there that allow you to watch other people play the game over the interweb. Perhaps the person you are watching has a very fast race time or are an exceptional sniper shot and you want to see how they do it. Or maybe you don't have cable and they are just some random guy you would rather watch than static. The difference here is that Smash Bros will allow you to bet on who you think will win the match you are watching. So if you think that Bowser will win the match then bet 200 tokens on him and see if you win. With your winnings you can use them to purchase various unlockable goodies in the game. Not to mention you unlock stickers while viewing and betting on matches. Not a clue what you do with stickers, but hey, at least you get something.
This does a few things for the online experience other than allow you to watch some random people having fun playing the game that you could very easily be playing yourself, no, it gives you a slightly different online experience. Now you are never certain if someone is betting on you when you are playing an online game (unless you are a loser and set "Allow Spectators" to NO, who would do that). You could be sitting at home playing a game online and lose someone a million tokens. You could single handedly destroy the last remaining hopes for a small family of 4 with nothing but a few measly little tokens remaining in their bank accounts. How do you feel about yourself now Bowser...HOW DO YOU FEEL?!!!?!!
