There are many advantages to having ROR over BeamNG. For starters, ROR is free and Beam costs around 20-25 dollars. Secondly, ROR is perfect for aspiring creators like me. Third, and most importantly, ROR is FAR less intensive than BeamNG will ever be, no matter what optimization is applied to the code, simply the amount of functions that are at idle when you start up the game will put tremendous loads on even a decent processor.
Also, for you roleplay fans, there is a character in ROR, and there is no rule stating you can't have actual car names as the mods.
