Two of gaming's biggest icons up sticks from Beijing to within earshot of the sound of the Bow Bells.
As we're walking into the Tower of London, they're helping out the Queen (or a very good impersonator). Further on, past the hordes of tourists peering at the magnificent prison-fortress through their camera viewfinder, there's a room full of seriously-suited business men and a sharply-dressed athlete or two. It's the most incongruous places to show off Mario & Sonic at the London Olympics we could have thought of.
Getting hands-on with the games, it's obvious the Wii version hasn't changed much from the version that sold a kajillion copies a couple of years back; the character line-up is identical, with four-player play and almost all the events from the first game returning. The styling has shifted to match the London background, which is thankfully more iconic to most gamers than the equivalent areas in Beijing were; Big Ben looms in the background, the horses ride beneath the Greenwich Observatory and badminton matches take place in the Wembley Arena.

There are just four new events: horse-riding, canoeing, football and badminton. The equestrian event (horse-riding to you and me) is played extremely straight and could have been pulled straight from Pippa Funnell; characters have to make their way atop a pony around a obstacle-riddled course in the shortest time possible. Canoeing is a two-player co-op game, which is all about your team's rhythm - paddle together and you'll zoom ahead. Badminton feels like a very light version of Mario Tennis or Virtua Tennis, with automatically-moving players wafting their rackets at the shuttlecock. If a player messes up their shot the opponent has a chance to do a special smash move, which is normally unstoppable. We didn't get to see the football, sadly.
