Well, games taught me English, which is kind of nice.
Another thing that might not have been mentioned yet, would be map reading skills.
A lot of games have maps, minimaps, radars or something similar. So most of us are sort of familiar with the concept, while an everyday person may go a year without ever having to even look at a map.
As an example, I was the only gamer during one NCO camp in the army, and easily beat the shit out of everyone when it came to navigating the woods with a map and compass. I had no trouble figuring out where I was, while other people would run like headless chickens, and often get lost in the woods.
