Microsoft Live Derby
To promote their Live Search Maps Microsoft have produced a Flash driving game, which allows players to drive on top of the satellite imagery of Microsoft Maps. Microsoft Live Derby is a Pacman type game in which you drive around picking up tokens whilst avoiding being hit by the other cars.
The game comes only a few days after we reviewed Tom Scott's Real World Racer for Google Maps.
There are also a couple of flying games for Google Maps, Wings and Goggles.
A game very popular on Digg at the moment is Statetris a Tetris clone in which players slot together American states rather than shapes.
