In this case, I don't think it can really be effectively copied/stolen. I have spent the last 10+ years getting myself well when doctor's claim it cannot be done. My oldest son has the same diagnosis and he is healthier than I am, so it is clearly replicable. The real reason I think the idea is important: I have spent at least five years trying to talk to people and put what I know into words on a website. And, for the most part, people just don't get it. I have concluded that I need a more information-dense delivery mode. I think writing a simulation (aka "game") will do the trick, or at least be far more effective than what I am doing currently.
Like with so many things, "the idea" may be just one piece of the tapestry of things which breathes life into a viable business or project. I was excited to hit upon this idea but remain frustrated at failing to execute (in part because getting myself healthier is still a big part of my life and I also have a full-time job). So I like this idea -- and it's so far not gotten me anywhere.
Peace.
