Rigs of Rods is an amateur project where the intention isn't to create a game but to create a realistic driving simulator. Driving simulator for all sorts of vehicles
That is the general premise of Rigs of Rods, that will allow us to drive trucks and cars, fly planes or sailboats with low-quality graphics but the most realistic physics. Nevertheless, sometimes it would be rather interesting to test how things really work in real life. Video games usually adjust their difficulty so that they work out to be entertaining.
