Chart Track reports that Wii Fit has made it five consecutive weeks at the top of the UK All Formats All Prices video game chart, fending off competition from Activision's X-Men Origins: Wolverine.

Sales of Wii Fit more or less remained flat (up 115 units over last week), but the Wii exclusive managed to outsell the multi-platform Wolverine by 1.7 to 1. Wolverine has to make do with a No.2 chart entry, although with a full week at retail to come, supported by the blockbuster movie, it could see a second week improvement. The game sold 51 per cent on Xbox 360, 39 per cent on PS3, while the remainder was spread around the PS2, PSP, Wii, DS and PSP.

FIFA 09 moves up one place to No.3 thanks to a 28 per cent surge in sales. There's also sales boosts for both Wii Play (+47 per cent) and Mario Kart Wii (+15 per cent) which climb to No.4 and No.6 respectively. Capcom's Resident Evil 5 is also showing strong legs, its No.5 position making it eight consecutive weeks inside the Top 10.

Atari's Chronicles of Riddick: Assault on Dark Athena is down 31 per cent to No.7, while EA's The Godfather II slides to No.8 on the back of a 22 per cent sales dip.

Outside the Top 10 there's a big boost for Street Fighter IV (+97 per cent) and Halo Wars (+75 per cent) which climb to No.11 and No.25 respectively.

With very few titles hitting stores this week - none of which look likely to chart highly - expect the current chart elite to battle for the No.1 spot.
