If anyone remembers the PS3 game Motorstorm, I believe tracks of that type would be great in the game with the right type of vehicles. Desert style maps are already very popular, but everyone wants to make a huge open spawrl. I would suggest in this case less could be more. Making a smaller lap based map with lots of small ramps and cliffs to jump down Depending the type of truck used this could be pretty awesome, even like a mod for Utah Map with something like this would be great. Something similar to the Track "Rain God Mesa" or "RockHopper" could be badass (Although some of those jumps are a bit unrealistic, but not all.) Rain God Mesa Rock Hopper
Hmm...I loved that game too, too bad they stopped the series...I am not that good at map making but I could try with some time and effort. so do you want it to be desert or jungle?
Desert for sure, which should be easier since you don't have to worry about grass or trees. I would love to make the map myself, but I have seriously no idea how to use the map editor. The main thing I was hoping to see in the map would be the small jumps between cliffs (like in Rain God Mesa), and maybe a big 90 degree wall of death turn like in both those tracks, Plus some medium size jumps. that a truck could handle. and a few small mud pits. Also for fans of the game here is a cool article I found from one of the guys who worked on designing these tracks in the original Motorstorm. https://www.reddit.com/r/gamedev/comments/25v02g/the_making_of_motorstorms_tracks/
