Currently, I am addicted to Guild Wars 2, but I've been there with many of the other usual suspects in the past.
I want to know how you have taken the magic ingredients that make games so addictive and used them to keep you motivated to make progress in specific aspects of your life, including the really mundane things like housework.
I've googled this, obviously, and looked at a sites like Nerd Fitness but they are a little too abstract on how you set the micro-goals to ensure that constant "just this one more quest" feeling that keeps you going until you reach Elite.
So, I want to know what you have personally gamified, and what tricks made it work for you. Any hidden gems also appreciated (e.g. for me duolingo.com
has transformed the way I learn languages with effective gamification).
