Weekly PC Sales: The Orange Box Reappears

Continuing its weekly tradition, sales-tracking marketing research firm NPD has released its regular list of the best-selling PC games at US retailers.

Covering the week of August 17 to 23, the list is mostly unchanged from that of last week. That may soon with next week's list, as that data will include sales of the latest Sims 2 expansion, Apartment Pets.

This week though, the only major difference from week's past is the surprise resurgence of Valve's mega-compilation The Orange Box, which contains Half-Life 2, Half-Life 2: Episode One, Half-Life 2: Episode Two, Portal and Team Fortress 2.
