Nearly 6.4 million video games were sold in the UK during December, a drop of nearly 8% over the year before.
2.85 million games were downloaded, while over 3.5 million games were bought physically.
FIFA 23 was the best-selling game of the month, followed by Call of Duty: Modern Warfare 2. Despite the PS5 and PS4's larger install base, Call of Duty: Modern Warfare 2's sales are relatively even between PlayStation platforms (representing 54% of sales) and Xbox consoles (representing 46%). The game was released close to major PlayStation exclusive God of War Ragnarok, which may have had an impact on the game's performance on Sony's formats.
