Personally I think the best attribute gamers bring to the table is an ability to “grind” through a zone until they level up, which is exactly how many people treat their career in help desk. Of course the challenge with that is focusing them to keep their skills rounded, or they can end up mid level with no method of further advancement (ala Skyrim.)
Still some interesting thoughts from the author. The trick of finding people that love what they do and are prepared to focus that passion is always going to be important. I do like Valves employee handbook though. It still remains for me the roll model for what I want our own IT handbook to be.
