Sandbox vs Railroad
Over the last few years this blog has focused on player-centric themes, by using a four-part method. This month I'm going to deviate a bit by covering a topic normally reserved for GMs, and by doing a long-form essay. If this approach works well, I might keep the longer once-a-month essay.
While the railroad/sandbox duality is typically considered a GM problem, it's still true that the Players must play in this duality, so this is a topic that's of importance to them as well.
