It seems like the World of Warcraft juggernaut has finally met a match - if perhaps only a temporary one. Since its release in November, the game's second expansion, Wrath of the Lich King, has ruled the sales charts in the US with an iron-gloved fist. Anyone who didn't see this coming, given that Lich King's predecessors were also chart-toppers, might have needed to work on their pattern recognition.All that we know is that DoW2 took first, Lich King second, then a double helping of The Sims 2, Spore, and two more entries for World of Warcraft and its Battlechest.

We'd crunch some numbers, but unfortunately, there don't seem to be any numbers to crunch.  Heartening news for Relic, considering that DoW2 did what F.E.A.R. 2 failed to do last month.Its time has come, though - after all, if there's anyone who knows how to kill (space) Orcs and (space) Elves, it's the Space Marines of Warhammer 40,000's Imperium. GI.biz reports that Relic's RTS has stolen the top spot from Blizzard for the moment.
