I found these videos showing that the game engine allows it and it works. I think this can be a great idea for future game development.
Suggestion for game development: trains and cranes.
I think there are a lot of different loading mechanics that would fit in the game, and this looks like it could be fun.
The train however, while a technical modding wonder, I don't think should be in the game. At least not drivable. "On rails" hardly fits the "off road" theme of the game.
@Lombra Farming Simulator is a game about a farm, crops and cattle, and you can cut trees and drive the trains, so ...
@knight25 Farm sim isn't a offroad sim though, hints the name "Farming Simulator"
not sure about drivable trains, but do like the idea of the ferry for crossing big rivers like i have seen on mod maps.
