The GFK Chart-Track list of the 20 bestselling full-prices PC games in the U.K. for the week ending September 27th is online, showing The Sims 4 retaining the top position, while FIFA 15 enters the chart at number two, and Stronghold Crusader II debuts at number five. On the all platforms top 40 FIFA 15 kicks even more ass, debuting at number one. Here's an overview:

The prelude to the all-important Q4 season begins in earnest this week with the ‘FIFA 15’ onslaught.

EA’s latest FIFA is the 21st in the main series, dating back to 1993 with FIFA International Soccer on Sega’s Megadrive (list excludes World Cup/Street/Management spinoffs). ‘FIFA 15’ accounts for 80% of all entertainment software units this week and a whopping 87% of revenue. Unlike last year, ‘FIFA 15’ debuts on 8 formats simulataneously - there are no more PS2/PSP versions this year and the later PS4/XO releases from ‘FIFA 14’ now arrive alongside all other versions.

Consequently, GfK Chart-Track total UK market estimates are that ‘FIFA 15’ is +15% units / +23% revenue over ‘FIFA 14’ (weeks 39 compared). If you align all the week 1 sales, so adding in week47/2013 PS4/XO sales (both Gen 8 versions launched in that week) then ‘FIFA 15’ is actually around the same in units and +6% in revenue. Finally, ‘FIFA 15’ Gen 8 versions (PS4/XO) account for 54% of sales units, with Gen 7 (360/PS3) holding a still considerable 45%. There were a few other new releases this week but the only one to make the Top 40 is Nintendo’s 3DS RPG adventure ‘Fantasy Life’ at No8 which is developed by Level 5, best known for the Professor Layton series.
