The new GfK Chart-Track Listing of the 20 bestselling full-priced PC games in the U.K. is now updated for the week ending February 16th. In space no one can hear you scream "we're number one," but as shown on the chart, Aliens Colonial Marines takes top honors this week, pushing Football Manager 2013 to number two. This is similar to the all platforms chart, where Gearbox's new first-person shooter is likewise number one. That's the only truly new entry on either chart, where some Sims 3 SKUs also reappear.
