bob_nj,

I have noticed that playing video games may improve your reflexes, but also makes your finger movements faster and sharper, which is not good for flying smoothly.
Actually, my son has a hard time slowing down his movements and inputs to the radio when he flies, and I believe it is a consequence of the games.

What has improved my reactions has been speeding up the models in my flight simulator.
A lot of crashes, yes, but they cost no money.
With time, I have improved the reaction time, to the point of giving some models more speed for practicing.
