Ubisoft's Assassin’s Creed has crept - like a stealth-elephant - into the Charts at Number 1 this week, bumping Call of Duty 4: Modern Warfare down to Number 2.

The Xbox 360 stock keeping unit (SKU) trumps the PS3 version, claiming 67% of Assassin's Creed's sales. The game is also the second fastest selling new intellectual property (IP) in history...ever... on an individual format... behind The Getaway on the PS2 – way back in December 2002.

It's also the third fastest selling 360 title within a weekly period, following Halo 3 and CoD4 - so that flies in the face of lukewarm reviews, one of which can be found right here.

Electronic Arts' The Simpsons Game is still hanging round at the top of the Charts at Number 3, losing just 9% of last week's sales. THQ's WWE Smackdown Vs Raw 2008 gets smacked down some, dropping two places to Number 4.

The superb Mario Galaxy performs disappointingly, failing to leap into the Charts any higher than Number 5. Rave reviews and not being able to get your hands on a Wii for love nor money nor non-loving sexual favours doesn't count for a huge amount, it would seem.

Dr Kawashima can't be put down, however, with Brain Training holding steady at Number 6. It also sees an impressive 67% jump in sales.

FIFA 08's still knocking about the Top 10, but it slips two places to Number 7. It meets Disney's High School Musical: Sing It! going the other way, as it climbs five places to Number 8 thanks to the release of the Wii version.

LucasArts' Lego Star Wars: The Complete Saga also climbs this week, Forcing its way up from Number 17 to Number 11 thanks to the release of Wii and DS SKUs.

More disappointment comes in the form of EA and Crytek's Crysis. The AAA shooter enters the Charts at number 14. Maybe Crytek was aiming a little bit high with the optimal specs...

Next week, watch out for (deep breath)... Guitar Hero III from Activision, Kane and Lynch from Eidos, Mario & Sonic at the Olympic Games, Mario Party for the DS and Need For Speed: ProStreet.
