Call of Duty: Modern Warfare 2 continues to dominate in December over in the UK. Activision’s title is keeping Assassin’s Creed II (3), FIFA 10 (2), New Super Mario Bros. Wii (4), and Wii Sports Resort (5) at bay. But talk about Nintendo pressure as 3 Nintendo titles all moved closer to the top 5.

The top publisher this week is Nintendo with six titles in the top 20. We’ll see what happens when Zelda: Spirit Tracks comes out. FIFA 10 is trying to battle Call of Duty Modern Warfare 2, but we’ll see if it can accomplish that goal next week.
