I just saw this on Tech Drool tonight.
GEwar is the first truly interactive game built using Google Earth. The game itself is fairly simple, but should provide some fun entertainment for you.
The basic idea of the game is this: You build armies to go around the world and capture cities. The cities all have a “value”, which is based on their population. The total value of all of the cities in your control is called your “total value”. The person with the highest “total value” is the one that is currently winning the game (and on top of the top players list). You can attack (and capture) cities using your armies. Armies (and other items) can be purchased using “Geos” that you can earn.
Once I get my PC that runs Google Earth up I’m so playing this.
