I've had some serious obsession with fighting games, I played street fighter 2 so much that I decided to take up Tae Kwon-Do lessons to be able to kick persons irl
And still whenever I play fighters or watch Kung-Fu movies I feel the urge coming up to fight

But I got way more self-control now than 15 years ago...thank god! Nowadays I only attack my girlfriend from time to time after watching a Kung Fu flick
