I recently downloaded
Rigs of Rods and I didn't find it available to add to my collection. I would have added it, but I am not sure how to classify it, given its abandonware, developed by fans, and has never been officially released. Some of the people who developed it initially went on to make
BeamNG.drive. If you can help me out or point me to a previous forum post on this topic, it would be much appreciated. Cheers!
