My wife did excellent work on a training simulator, and regularly impressed both the military customer and higher ups on the corporate side. She credited three video games with building her most impressive skills: Descent taught her to visualize and maneuver in 3D space, Starcraft taught her to think about force composition and disposition, and Nethack taught her to make thousands of decisions (and type thousands of characters) without making mistakes. She still games pretty extensively (she'll be taking Tuesday off for the SC2 expansion), and has a great job and family. And at least part of her excellence is due to the way she uses video games to sharpen her mind.
