After enough FPS games, I tended to circle-strafe alot; usually whenever I worked as well. Surprisingly, it improved my effectiveness at all my past jobs.
After a bit of Tetris, or watching my computer optimize, everything I see around me can be arranged to make the most of what space is available.
After enough similar adventure games or reading manga, I can see what people are saying, and log them down in my head, as well as display a series of possible responses (with odds of effect next to them). Similar can be said about being on the forums for too long.
And after enough DF, I can read emotions and all sorts of other parts of life like the DF interface. Similar can be said about Sims games.
I think the most useful "disorder" I got had to be from playing enough Gran Turismo. My driving skill (along with fuel efficiency), of course, following law, improved drastically. Adapting that game into skill is actually rather simple, provided you're familiar with your vehicle of choice. If you know how to draft without tailgating, and know how to properly overtake, you can really save up on those longer trips. It actually gave me an interesting racing idea which makes use of your resourcefulness (in regards to traffic) as well as good training of getting to places quickly while following the law. Speed limit racing. More challenging than it sounds, especially if you start at the same time against someone else you're racing to the destination with. Red and yellow lights can either be your best friend, or worst enemy. Back roads are rather helpful too.
Especially when going to classes, I usually set my stopwatch, and time myself to arriving at my destination. I got some really good times, and I really streamlined my driving skills and path to my destination. Didn't have to stop for gas half as often.
