I wouldn't mind revisiting it someday, there were a bunch of things I couldn't do in the original for technical/sanity reasons lol. If I were to do that I'd definitely look for a lead programmer that wasn't me, at the very least, since I'm also pretty tangled up with another large personal project and it would really benefit from someone with better technical skills. As far as folks using the idea I guess just go for it, haha. I mean it's out there now, and if you'd like to expand on it then that's cool.
