Case: Chorewars

A good example of how games can make something as dull as chores fun is chorewars.com. Here you get to create an avatar starting at level 0 with a set of skills. As you complete chore adventures (you specify the adventures yourself as well as the monster you can encounter and the loot to find) you will gain exp and improve different skills. Your avatar can be compared to the others in your household to see who is the choreking!
