There have been a few people that tried, there was a small group that used to be active in the community back when Sim Monsters was originally created that were aiming for a complete simulation experience. I know Klayton was working a Lucas Oil Crusader/ Son Uva Digger that were proper node beam structures that could break. I also know Matt Wilkinson was working on a partially breakable node beam, basically 4 links would bend, swaybars, tires that could deform to simulate "deflating". But none of this stuff has ever been released as of now. ROR is kinda of limiting but also has the ability to do quite a bit, it is a very difficult for people to grasp. Do not believe me? Browse around a truck file, modding for ROR is not user friendly (Beam NG is even worse). Now imagine having to scratch build well over 150+ trucks, ontop of that, now deal with brand new trucks debuting, trucks you finish or currently working on get retired. I have a hard enough time keeping up with chassis's.
Right from the beginning this community grew big way to quickly. There was/still is not enough hands to help build it, and the members on here have lives outside their computer monitors.
