GTA IV outsells everything. Ever. Especially on Xbox 360
Just in case you've been too busy playing GTA IV to keep up to date with sales news, here are the figures: the game shifted 3.6 million units on its opening day and six million in the first week, pistol-whipping all previous records to the ground. The estimated retail value so far? $500 million. That's $100 million better than Pirates of Caribbean 3. In your face, Disney family entertainment!

Microsoft has muscled in on the GTA IV stat fun claiming that the Xbox 360 version of the game has sold over 100,000 more copies than the PS3 version in the UK. From the gloating press release:

Data released by ELSPA/Chart-Track shows Xbox 360 Week One sales at 514,000 copies sold in the UK. PLAYSTATION 3 version of the game sold only 413,000 copies, clearly demonstrating that gamers prefer the Xbox 360 version. Xbox 360 console sales jumped 125% reflecting the popularity of this franchise on the platform.

The release goes on to claim that 9.7 million hours of Grand Theft Auto IV online multiplayer have been played over Xbox LIVE, while 31 million hours have been spent playing the game overall.

Meanwhile, on the UK game charts, guess what's shot to number one this week... That's right, it's Iron Man: The Official Videogame! No wait, GTA IV.
