Nrik noted a wired story about too much gaming and how sometimes a few too many hours of gaming can cause your mind to blur some lines. For me it was Tony Hawk- I played so much that I started sizing up curbs for grinding while driving home from work. Katamari Damacy has been a problem too. I'm fairly certain my car is large enough to pick up the railings on the overpass near my house. I'm even more certain that these thoughts are bad.
