Weekly PC Sales: Left 4 Dead, Lich King Reign

It's an undeadly sort of week for NPD's PC gaming sales chart, with Blizzard's World of Warcraft: Wrath of the Lich King and Valve's Left 4 Dead taking the top spots on the US list for the week of November 16-22.

Sadly, PC juggernaut Nancy Drew: The Haunting of Castle Malloy has finally fallen from the chart, replaced by the Spore and Fallout 3-beating EverQuest II expansion The Shadow Odyssey.
