Rockstar’s Grand Theft Auto IV has crashed straight into number one spot in this week’s multi-format charts, outselling last week’s big release, Wii Fit by 9 to 1.

A few more figures from Chart Track reveal that the controversial title made up 61.2% of all software sales last week with over 1 million copies sold in less than a week since its release.

Wii Fit drops to second position with sales down by 58%, probably because no-one can find a copy to buy, and the only other new entry this week is Iron Man, which has been released on every format out there.

We didn’t think much of the DS version, check out our Iron Man review.
