You get 3 versions:

-The Trail where you can choose yourself how hard your challenges wil be
-The City where you can replace the standard vehicles with futuristic ones. Just browse the vehicle base here for REPLACE and look for futuristic vehicles as you see in the pictures. Replace the planes with space ships and see them flying over you while you cross the mountain trails.
-Also both combined if you have a powerful system.
