Rigs of Rods is an amateur project where the intention isn't to create a game, but to create a realistic driving simulator. Thus, every design must have realistic characteristics and features. This means that the chassis and tires of each vehicle that we drive will have the same proportions and characteristics as they would in real life.
The game offers several settings to test the trucks, cars, boats and planes, and the OpenSource community that has developed around the game has published various modifications (mods) for the game.
Even though the game is amateur, we will have at our disposal many effects that are implemented in commercial games, like HDR, antialiasing, pixel shader support, but the most important feature is the realistic implementation of physics in both the vehicles and the environment.
On the other hand, it's important to state that this is a pure simulator, it doesn't include any type of help option, and the application is configured by means of another executable, not the one used to launch the application.
