How to Play Roleplaying Games

From the introduction to the document:

For the past ten-plus years of my life, I’ve been writing roleplaying games. I’ve been playing them for much longer. Back when I started, you could abbreviate “roleplaying game” to RPG without people immediately thinking about “rocket propelled
grenades” and the acronym is still around causing
trouble today.

In that time, I’ve watched the market bulge, shrink, grow, recede and, constantly, change. The consensus as I write this is that the hobby is shrinking. To counteract that, of course, we need to recruit new players. Hopefully, that’s you.
