Rigs of Rods: a soft body
physics based vehicle simulator with support for driving, flight, and sailing. It offers a variety of functionality from multiple transmission types, offroading, flight and buoyancy mechanics, throttle-
based hydraulics, advanced steering types fully-deformable
beam-node structures and contactable
sub-meshes for collision simulation.
Originally developed in France by Pierre Michel Ricordel (Pricorde), RoR was designed as an open source trucking simulator, depending on user generated content to stay interesting.
It's successor BeamNG.drive is a pay to play driving game in public alpha, thus far offering much less functionality and content than it's free-to-play counterpart.
Shane: "Are you playing that awful driving simulator again?"
Fred: "
Shut up Fred, RoR is awesome,
best physics of any game!"
Shane: "But it's not a game, there's no objective!"
Fred: "Who cares, I can independently adjust the friction coeff..."
Shane: "Exactly why it's not a game"
