When starting on answering a question, you begin at the very basics, cases for which you have few open questions (like "what is an RPG?", what qualifies as, "some design space?" and so on). As for wanting to play, about 75 million people in the world know how to play Go, and there's something over 20 million current players. of the game. If you don't like Go, you may substitute Chess, which has over half a billion players - it has Fool's Mate, which some might consider "breaking", so I started with Go. I'd expect that is generally accurate. Half a billion and more chess players are glaring at you. "Fun," is subjective, anyway, and so won't help you. I mean, duh. This is an RPG site. But if you want constructive discussion, you start with the easy case, and add complexity bit by bit. Jumping to the end leads to lots of unanswered questions behind you that may invalidate the thinking. Work with me here.
