Right now the crop field 1 or 2 are great however for american maps we need the big crop which is corn. The issue with corn is its much taller than the other "crops" in the game. So it might have to be generated like a forests to prevent players who are in the corn field from being visible to players outside the cornfield like what is possible with tall grass.

If this is taken up seriously it could also benefit gameplay to make vehicle tracks that permenantly run over the corn , similar to how it works with the grass in game now but they dont "bounce back"

Also sound effects for the heavy corn hitting the vehicle
