Microsoft has just launched an advergame to promote its Live Search Maps. Created by EVB, Microsoft Live Derby 2007 it's a sort of revisited "driving" version of PacMan.
You can select to run in five different cities and decide among four crazy drivers (I picked the Golden Oldies...) who will take you around the map collecting "pills", avoiding other cars and reaching a series of key destinations.
The game is fun to play, and it's less easy as it might appear at first sight. I tried three times and I didn't manage to pass the first level... but maybe this is because I'm not a very good virtual driver ;-) I'll try again!
