First Attempt : Operation Failure

After building all of that, when I looked at my kingdom, the buildings looked too simple for my taste so I went to each building in Google Maps through Street View and copied the detail to my file by texturing it, making windows and making roofs.When I first tried to use game, a lot of things were very hard such as grass and snow is not allowed in the game engine and the car keeps falling into the road.I decided then to animate it so then the car follows a invisible line which is a path going to every corner of the village but sticking to the roads.
