i'd like to see that in arma3, however, not cause it's great but rather cause it's much better than arma2. the comparison with other games is needless, that thing is far from ideal but even so it's far better than a2 and that's what matters the most.
although if bis guys really plan to implement something like that, it wouldn't hurt if they take it for serious and make it less "Hollywood look alike"...doors don't just fall off so easily, hub neither. vehicles don't perform that crazy Hollywood "reverse somersault/half-somersault" thing upon impact or crash. it's a factious nonsense, the vehicles don't go up into the air when they collide on a level surface.....not to mention a heavy military vehicle.
