I didn't learn anything from hours of Counter-strike, half-life, flight sims (ok this taught me some aviation trivia) as a teenager. I deeply regret these hours, as I could have spent them outdoors hiking, rock climbing, running. Maybe even talking to girls and building better social skills.
I thought the same about my passion for Lego-style construction toys. Then, as a 25-year-old, I had to build something out of cardboard with people about the same age. It was really surprising to see that they had no intuitive understanding at all of trivial things like "which side do I start from" or "this thing is wobbling and needs a little reinforcement at the corner" (I am not talking about "complicated" things like gears and robots etc.). So, who knows what you learned from those games?
