Once deadly rivals, Sonic and Mario were always likely to kiss and make up after Sega left the console-building rat-race. Sure enough, they have, against the backdrop of an officially licensed 2008 Olympics game. And they've brought their mates - Wario, Luigi, Peach, Amy, Knuckles et al.

As you'd imagine, Mario & Sonic At The Olympic Games is much like Daley Thompson's Decathlon updated for the Wii, with countless pleasingly diverse events (including rowing, diving, swimming, trampolining and archery), each with a quirky system that will have you gesturing wildly. The more arcane ones require practice before you master the controls, and little attempt is made at a coherent single-player game.

Hardcore gamers will, no doubt, turn their noses skywards when they see it, but its infectious and addictive nature, particularly when played against others, renders it classic post-pub, party-time Wii fare.
