The UK all-formats chart has settled into a familiar rhythm after a helter-skelter November, with Call of Duty: World at War top of the pops once more.
Of the new releases this week, the excellent Resistance 2 performed decently - despite the EUK supplier shortages reported by GamesIndustry.biz - and placed at number 10. Sales of the sequel were only two-thirds those of the original game, but there were considerably less shooters (not to mention games) on the PlayStation 3 back then.
Faring much worse was poor old Sonic, who Unleashed himself not into the all-formats top 40, but instead into the Xbox 360 chart at 23 and the Wii chart at 34. He failed to place in either PS3 or PS2 lists.
However, last week's newcomers gained momentum. Need For Speed: Undercover upped a gear to race from five to two, and Tomb Raider: Underworld climbed from nine to seven.
Elsewhere, FIFA 09 was at three, Mario Kart Wii at four, Brain Training at five, PES 2009 at six, Wii Play at eight and Guitar Hero World Tour continued the series' strong sales to stay in at nine.
Lower down the chart, Fallout 3 hopped up 10 places to 13, keeping its radioactive core humming, and last year's Project Gotham Racing 4 gained yet more unexplained momentum to get to 26 - presumably as part of a bargain price deal.
LittleBigPlanet kept on tumbling down to 32, as did Left 4 Dead, which dropped considerably to 34. Both Midnight Club and Mirror's Edge also fell, slipping to 36 and 39, respectively.
Falling off the list this week are Professor Layton and the Curious Village, Saints Row 2 and World of Warcraft: Wrath of the Lich King.
