The Sims 4: Get Together debuts at number two on the GFK Chart-Track PC top 30 chart for the week ending December 12th. Football Manager 2016 retains the top spot there, while Call of Duty Black Ops III squeezes into the top spot on the all platforms chart. Here's the write-up which also mentions an extra chart will come this year:

This is the week 50 chart, but thanks to the Gregorian calendar this year is also a 53 week year (last occurred in 2009).

Consequently, the last published chart before Christmas will be next week and that is the definition for the Christmas Chart (week 51, ending Saturday 19th December). Jockeying for position and next week’s Christmas No1 is looking like a 3 horse race. Activision’s ‘Call of Duty: Black Ops III’ climbs one place to No1 (-37%) – last year Activision held off EA’s ‘FIFA 15’ as ‘Call of Duty: Advanced Warfare’ was the 2014 Xmas No1. At No2 this week is EA’s ‘Star Wars Battlefront’, up from No3 (-22%) – this title could benefit from Star Wars 7 movie mania, released in just a few days. EA also have ‘FIFA 16’ which drops 2 places to No3 this week (-49%) but ‘FIFA’ games currently hold the record in terms of Xmas No1’s with 8 so far. Records for traditional entertainment software Xmas No1’s actually date back 32 years to 1984 and although the charts back then were very different it was in fact Activision’s ‘Ghostbusters’ on Spectrum and Commodore machines that claimed the first ever Xmas No1 (week 51, 1984). Bethesda drop one place to No4 with ‘Fallout 4’ (-21%) and Telltale Games’ ‘Minecraft: Story Mode’ climbs 2 places to No5 (-3%). Last week’s 2 big new releases drop places, with Square Enix’s ‘Just Cause 3’ down 2 to No6 (-43%) and Ubisoft’s ‘Tom Clancy Rainbow 6: Siege’ down 3 places to No9 (-58%). The lone new entry this week is EA’s ‘The Sims 4: Get Together’ debuting at No38.
