Want to gamify your life? Gain experience for checking items off your to-do list. Set goals and get points for reaching your milestones. Battle evil villains with every task you finish. Collect random crap, I mean gear, and raise pets. Then head over to www.habitca.com and join the fun!
It sounded fun so I joined in. It's actually getting me to do some of those things I've been putting off forever. But the whole system runs on your personal integrity. Want to create stupid tasks just so you can level up faster? Go right ahead. I put "get dressed before noon" and "drink water" on my list. Easy enough to do, but still things I sometimes need motivation to accomplish.
There is some interesting research on gamification of things like school and life. Here's just one example. Short answer is yes, it can work. But a lot of users will drop it once the novelty wears off. Some of the research found that over the long run, gamification actually decreases involvement. People come to expect a reward for doing things that they did before the game without reward. Make the reward too difficult to get or not rewarding enough and people quit.
Check it out if you're interested. For me, it's working for now. When it stops working, I'll find something else.
