UK Charts: Mario & Sonic regains lead

Mario & Sonic at the Olympic Games has returned to the number one position in the UK's All Formats Top 40 chart according to data released by Chart Track.

It is the third different title to reach the top spot so far this year in as many weeks, as Activision's Call of Duty 4: Modern Warfare dropped to second place.

Nintendo exclusives - either for Wii or DS - made up over half of the All Formats Top 10 charts for the first time since September 2007.

With the exception of The Simpsons Game, which moved up one place, every multi-format game in the top 10 lost sales. Sega's Ghost Squad and Capcom's Zack & Wiki debuted in the Top 40 charts at number 20 and 25, respectively.

For the week ended January 19, the top selling games in the UK were:

1. Mario & Sonic at the Olympic Games
2. Call of Duty 4: Modern Warfare
3. The Simpsons Game
4. Dr. Kawashima's Brain Training
5. More Brain Training from Dr. Kawashima
6. Assassin's Creed
7. FIFA 08
8. Super Mario Galaxy
9. Guitar Hero III: Legends of Rock
10. Wii Play
