GTAIV boasts 40% attach rate with new 360s

Grand Theft Auto IV is selling very well (perhaps you've heard), but did you know that it's also moving Xbox 360s at a blistering pace? On a recent Major Nelson podcast, co-host "e" revealed that GTAIV boasted a 40% attach rate with new 360s during its first week of availability. "The game is attaching well to new consoles, roughly 40 percent of 360s going out the door had a copy of GTA IV going with them," said 'e'. With only the UK sales numbers for GTAIV currently revealed, we'll have to wait for the worldwide 360 numbers before the full significance of the attach rate really means. Whatever the actual figure, we're willing to bet that 40% of all 360 copies of GTAIV represents a lot of consoles.

While there's no way to prove that consumers bought their new consoles specifically to play GTAIV, there's no denying that it helped drive sales. We'll have to wait for the latest NPD numbers to see just how big the GTAIV effect was.
