I made a bracket for this just for fun. Got 12-4 so far after the first half of Round 1. I just went with all the popular ones as best as I could. The contest is kind of fun but not the best design. You either choose your favorites to win, in which case you have no chance of winning, or you choose the ones with the best odds, in which case you might win at the cost of not being faithful to the games you like.

Also the best gamespot people left. They are at www.giantbomb.com now. It's a similar kind of site but much smaller. They are more fair without the big sponsors/ads pressuring them to give out perfect scores. Also each game has a landing page that can be edited like a wiki, so the whole site is almost like the wikipedia of games.
