After just two weeks at the top of the hill, Dawn of War II has now been given a shove down to third place by Creative Assembly's Napoleonic RTS, Empire: Total War. This week also saw the recently released F.E.A.R. 2: Project Origin start to slip down the ranks from number four to number 8. Meanwhile, Spore has re-entered the top 10 again after falling down to number 11 last week. You can see the retail top 10 for the week ending 7 March below:

01 Empire: Total War (New entry)
02 Football Manager 2009 (No change)
03 Warhammer 40,000: Dawn of War II (Last week: 1)

There's been little in the way of big changes further down the chart this week, although both of last week's major new entries, Men of War and Tom Clancy's EndWar, have taken a good battering already. Men of War is already on its way out at number 20, while EndWar has been knocked down from number 9 to number 14. You can see the retail top 20 for the week ending 7 March below:

11 Fallout 3 (Last week: 13)
12 Call of Duty: World at War (Last week: 10)
13 World of Warcraft: Battle Chest (Last week: 12)
14 Tom Clancy's: EndWar (Last week: 9)
15 CSI: New York (No change)

It's interesting to see how a special offer can affect the Steam chart from week to week. Last week, Lost Planet: Extreme Condition re-entered the chart because of a cut-price deal, and this week has seen a similar occurrence with Unreal Tournament 3 Black. The Black edition of Unreal Tournament 3 includes the new Titan Pack, which features 11 new multiplayer maps and two new game modes called Greed and Betrayal. Until 15 March, the game has 40 percent off its usual price of £13.99, meaning it's now currently available for just £8.39, which explains why it's gone straight in to take the number 1 position. Similarly, World of Goo has also re-entered the chart at number 6 after a cut-price deal this weekend. See the full Steam top 10 below:

01 Unreal Tournament 3 Black (New entry)
02 Empire: Total War (Last week: 2)
03 Left 4 Dead (Last week: 4)
04 Empire: Total War Special Forces Edition (Last week: 2)
05 Warhammer 40K: Dawn of War II (Last week: 3)
06 World of Goo (Re-entry)
07 Counter-Strike: Source (Last week: 5)
08 Team Fortress 2 (Last week: 7)
09 Total War Mega Pack (Last week: 6)
10 The Orange Box (Last week: 9)
