Joel Shempert has given Willem Larsen's "Pedagogy of Play" (Parts 2, 3 & 4) a new name: "Fluency Play." I rather like it. He's posted about it both in a thread on Story Games, and in a blog post. He provides a nice summary of what it means, too: "...basically instead of trying to assimilate an entire body of RPG procedures and put them into action from the get-go, you start at the most basic level and work your way up. The aim is to have a game experience with maximum creative flow, where the shared dreamspace is as unbroken as possible. So you only play at the level you're fluent at."
I've posted a good bit about "fluency play" here before, under the old, alliterative name. I like this term, and it does my heart good to see people responding to it, at last. In the thread, In the thread, Hans Otterson noted that it seemed like a way of hacking existing games. I can certainly understand that view. After all, games up until now have generally expected you to learn all the rules at once, sit down, and start playing. If fluency play can happen, it must then happen by hacking existing games to suit it—as Willem & I experimented with Polaris, or as I & Sean Nittner experimented with Mouse Guard. That said, I took Willem's description as a call to designers to design this into their games from the start. The version of The Fifth World that I'll soon start playtesting will have this. Reading the rules will form part of the game itself, and that will add rules, bit by bit. I look forward to playing other games that take this approach, too.
