The NPD Group always announce the ten best-selling games for the previous month first. Let the glory boys get all the attention. Then, on Friday, they quietly pay respects to the ten games that didn't quite make the cut.
Those ten games, running 11-20 on the charts, can be found on Gamasutra, and what a pitiful bunch they are. For reference, Madden 10 on Wii only sold 67,000 units across the United States, meaning in August for a game to make the top 20 it simply had to be released.
