Ok. Someone introduced me to Chore Wars and I am thrilled. We have been doing it for 3 weeks and I love that Ben comes to ask me -- are there any more chores I can do?!
It basically works like Dungeons and Dragons. You set up all of the particularly tedious household chores as adventures. Each adventure had experience points, a range of gold pieces, and the potential for treasure associated with it. So, for example, emptying the dishwasher earns you 20 XP, 10-40 gp, and the potential for a Fizzy Potion (soda) or Pokemon Card. GPs can be redeemed for treasure from the treasure chest or real cash at an exchange rate of 100 gp/ $1. At least that is how I set it up for our household.
As you do chores you gain experience, move up levels, collect treasure, and get gold. Tonight both Ben and Nikki used up a Fizzy Potion at the restaurant to order Sprite (normally they are only allowed to order water or milk).
Oh... did I mention it is FREE?! And the kids are ASKING for more chores to do during their free time!
