Rigs of Rods (RoR)

Billy found this little gem, and I thought a few of you here might be insterested in having a look. It's an open source simulator for nearly any type of vehicle with an excellent physics engine and graphics. Online multiplayer with races is a nice touch, you can have a destruction derby with cranes and shit. Its still in beta so its a bit buggy, but it shows a lot of potential. So everything related to this game can go in this thread.
