Seems you're familiar with the idea. However, as with many new ideas gamification is still so early in its lifespan that people might be using it wrong. To me it is an ideal, more than a method. As far as I know, there isn't any one way of doing "gamification", therefore I see it as an opportunity to bring what is great about childhood to adulthood in an acceptable manner. But in all honesty, I've never given it a try. No such projects so far in my career. Ideas are always easier than results.
