Have you ever considered starting a Kickstarter campaign to raise the funds to make upgrades to Chore Wars?
I began using it the other day for language learning incentive (thanks to a mention in a blog by Rosetta Stone) and would like to see it grow and become even more useful. I see several uses for our family and my husband's middle school classroom. A Kickstarter campaign (which musicians and filmmakers often use) would provide money up front and if as many people like Chore Wars as it seems (from what I've read on this website), then you should be able to fund the upgrades without much difficulty.
