January's Top 20 PC Games Revealed by NPD

Compiling all the data from its weekly sales offerings, marketing research group NPD has issued a list of the best-selling games at U.S. retailers across January 2009.

The actual contents of the list haven't changed all that much compared to December, as most of the games just shuffled positions, though the StarCraft Battle Chest, Civ IV and two slot machine games replaced GTAIV, two Sims 2 expansions and Nancy Drew.
