GfK Chart-Track is back on track, as its rundown of the 20 bestselling PC titles in the U.K. is out on Monday again this week. The boggling success of Football Manager 2011 continues, as it knocks Portal 2 out of the top spot this week. The big winner for the week is the Empire and Napoleon Total War Collection, which jumps all of four spots to #11, while on the downside, Darkspore drops six spots to #18 and RIFT drops six places to #13. MCV has word on the U.K. all platform chart, where Portal 2 was supplanted at number one by Zumba Fitness. On a related note, please remember, you can do anything at Zombo.com.
