GfK Chart-Track once again offers their list of the top 20 bestselling full-price PC Entertainment titles in the U.K., this time for the week ending December 17, 2011. This week Football Manager 2012 retains the top spot on a ;list where the only change in the top 10 is the eight and nine spots swapping positions. The new all-platforms chart for the same period is almost as stable, with 19 of the top 20 returning from last week.
