Market research company NPD Group has released its list of best-selling PC games for the week of December 21 – 27, 2008. Ever since it debuted, Blizzard's World of Warcraft expansion, Wrath of the Lich King, rose to the top of the sales charts; this past week was no different. Following behind in second place during the week of Christmas was The Sims 2 Double Deluxe. While this week remains very similar to the prior week, Activision's Call of Duty: World at War did drop and swap places with The Sims 2 Apartment Life.
