Chore Wars

Interesting beta site that uses some of the RPG game elements to reward people for completing tasks.

It can be used by households, offices, anything you can think of. There are 'quests' and even battles (although they do not affect the outcome). Users log in to their character's account in their party, and if they complete a chore, they receive a set amount of XP points. Essentially it is a means to keep track of what got done, and weight the tasks.
