Sales of GTA IV dropped 22 per cent in the week, but it still manages to hold onto its coveted top position.
Sega's Mario & Sonic refuses to stop bothering the top five, rising from fourth to third with a 66 per cent rise in sales as a new, glamorous TV marketing push begins.
Nintendo's Wii Play rises from fifth to fourth with a 40 per cent increase in sales, but it's another Wii title that might snatch the most interest from industry watchers: despite mass popularity, Wii Fit fails to chart in the UK Top 40 for the second consecutive week.
Konami's Pro Evolution Soccer 2008 takes fifth place, up two places from last week, whilst Ubisoft's Haze drops from No3 down to sixth.
Elsewhere, Eidos' PC-exclusive Age Of Conan tumbles from No.2 down to 16th place, whilst Sega's Superstar Tennis rises from 15th to seventh.
