It was recently confirmed that The Sims franchise has sold over 100 million units, and the recent release of the Sims 2 FreeTime Expansion Pack ferociously leads that freak occurrence . Compared to February’s NPD totals, the March release of Dawn of War Soulstorm Expansion Pack nabbed the second spot away from Sins of a Solar Empire which has moved down to a respectable 5th place. Last months’ first place winner, Call of Duty 4, drops to 3rd place and the World of Warcraft: Battle Chest drops concurrently to 4th. The Kane’s Wrath Expansion Pack, which released late March managed to "command" a 6th place presence. Somehow the jewel case version of Advanced Warfighter snatched the 7th position. All things World of Warcraft continue to stay in the top 10, while Frontlines: Fuel of War nabs the tenth spot away from Crysis
