I have both of those, and there's a thread on BeamNG (Drive).
NCG is a lot of fun, however when parts stop working isn't realistic, but still... a hell of a lot of fun. I can't wait for multiplayer... if vehicle sync doesn't spaz out because of lag... Oh and soon they're going to hopefully add more thud to vehicle impacts, which it really needs.

Haven't tried BeamNG in a while. It's pretty cool and is trying a more technical approach to vehicle handling/tires/suspension. My problem with the original couple/few vehicles is that, yes they're trying to have simulation and traction for all 4 tires, but on the first vehicles, the tires bounce rapidly like a racquetball under your hand, which causes them to lose traction. But it's improved with newer vehicles. Looks like I gotta try it again...
