Is there a place where you can see the monthly sales for games?

Much like how Nielson tracks ratings for T.V. shows and Nielson Soundscan tracks weekly sales for music albums, is there a place to see the monthly(or weekly) sales for video games? It would be interesting to see how our favorite games are doing. In my EGM, Super Smash Bros. Melee is always in the top 10 for Gamecube games, and I wonder how much it sold so far.

Try the G4 show Filter's website. They often have a poll on the show and probably have it on their site.
