While the NPD Group has ceased providing weekly sales charts for the boxed-copy PC market in the US, it still hands out its monthly - and often hilarious - lists. Let's look at February's.
As you'd expect, they look a little different to those found on Steam or Direct2Drive. While those are often quite contemporary, and full of games targeted at the "hardcore" crowd, NPD's charts are full of Sims games, Sims expansions, old Blizzard bundles and more Sims expansions.
