Google earth (and maps on the desktop) contains a lot of 3D landscape and building data. While not exactly looking like professionally sculpted recreations of the cities, using the desktop client of google earth to take a stroll through the streets of Valetta was a nice experience.
This got me thinking: Are there any games already utilizing this data? I was thinking along the lines of jump&runs and flight simulators.
I could find several games making use of Google Maps satellite images or Streetview data, but I couldn't find anything making use of the 3D features.
