The Wii's revolutionary fitness game (if it can be classed as such) is selling rather well in the UK...

The latest sales figures from Chart Track show that Wii Fit has debuted top of both the Wii and All-Formats chart, selling to a tenth of all UK Wii owners in just its first two days of release.

This means the title has already beaten previous Wii top-seller Mario Kart Wii, and is in fact the third fastest-selling title of all time in the UK, behind GTA: San Andreas and Halo 3 - and the title retails at a significantly higher price than both.

Mario Kart Wii, which last week had sat atop the All Formats chart itself, was pushed down to number two, with the third spot being taken by Mario & Sonic at the Olympic Games, which continues to sell phenomenally well.

The top three titles all Nintendo exclusive? Who'd have thunk it!
