Thanks to the start of the Olympics, London 2012: The Official Video Game of the Olympic Games sales were up 25 percent last week in the UK, helping the global event tie-in game step up to the top pedestal.

The official game, which held the silver last week, wasn't the only Olympics game to benefit from the event's starting gun. Mario & Sonic London 2012 Olympic Games also saw a bump of 21 percent, raising it from eighth to bronze. Lego Batman 2: DC Super Heroes finds itself wedged between the two sports minigames in silver.

Pokemon Conquest was the only new title last week to break the top 40, storming spot 17 in its debut week. Now we wait to see if the Pokemon X Nobunaga's Ambition franchise crossover transitions poke-fever into a desire to buy strategy games based on feudal Japan. Scout out the UK top ten after the break.
