playing "excitebike" makes you a very crumby motocrosser in real life. I know that for sure. Gotta believe flying areal fighter in real conditions, has very little in common with what we do in here.
I can't see that motocross on a simulator would have anything useful to translate to real riding of motorcycles. That's my opinion having done a large amount of off-road riding in my life on motocross bikes.
Flight simulators are a totally different matter. That's my opinion having done both a large amount of flying of AW and AH, having flown normal private planes (like Cessna 152's), and having flown at Air Combat USA in dogfights with other planes.
I think the ACM, gunnery, and situational awareness folks learn here in flying around simulated WWII planes would substantially translate to flying real WWII-class planes in dogfights.
