Market research company NPD Group has released its list of best-selling PC games for the week of November 30 - December 6. Nabbing this week's top spot was Blizzard's World of Warcraft: Wrath of the Lich King expansion, which continues its financial reign. The first week of December bumped Call of Duty: World at War's position from its previous week's seventh placing to fourth. Fallout 3, Bethesda Softwork's critically-acclaimed RPG, reemerged on to the top 10 and garnered a fifth spot. Another game to reemerge on the list was Ubisoft's free-roaming first-person shooter Far Cry 2. Coming in seventh was the PC debut of Rockstar's smash hit, Grand Theft Auto IV.
