I am now GMing two games and playing in two games online in addition to GMing a game at home for my kids. I've started a very minor world building exercise for one of my games. I would like to take the next step (logically, in my mind) and generate some income from these activities. (If for no other reason than to say to my wife, "But, see honey, I'm making money when I do this!") What are the options, which are most likely to generate income on a consistent basis, and am I just fooling myself thinking this is something I could do?
