Well, we honestly thought Halo: Reach would keep its #1 position for weeks to come, but after a week on sale it has been usurped by Codemaster's F1 2010. Not only that, but according to GfK Chart-Track, the racer beat sales of both Bungie's prequel and Dead Rising 2 combined this week.
(NE) - 1 - F1 2010 - Codemasters
(1) - 2 - Halo: Reach - Microsoft
(NE) - 3 - Dead Rising 2 - Capcom
(NE) - 4 - Civilization V - 2K
(2) - 5 - Sports Champions - Sony
(NE) - 6 - Guitar Hero: Warriors of Rock - Activision
(5) - 7 - Prince of Persia: The Forgotten Sands - Ubisoft
(3) - 8 - Mafia II - 2K
(4) - 9 - Toy Story 3 - Disney
(NE) - 10 - Final Fantasy XIV - Square Enix
A slew of highly-anticipated new releases pepper the Top 10 as well, as Dead Rising 2 performs well at #3 and Sid Meier's Civilization V hits #4 after a five-year long wait. Previous #2, Sony's Sports Champions, settles for #5.
The new Guitar Hero game rocks its way to 6th position, and Final Fantasy XIV was released on the PC to a good reception, rounding off the Top 10 quite nicely. The Square Enix MMO's launch this week was for the Collector's Edition, with a second launch next week for the Standard Edition. An interesting way of going about a game's release, that.
