I’ll second what Patrick Riegert said, but with less experience, since I only sat in on the one SWvM game (where this image was from).

I’m a fairly visual learner, and this helped me remember key facts. Honestly, I rarely looked at the paper once it was written out, but it was essential the few times I needed to refer to it (and I’m guessing helps eliminate many of those “who is that guy, again?” type questions from the players). Also, just seeing it laid out spatially helps me internalize many of the relationships and components in the game.

I think this is KEY: “It is a central and theatrical process, which draws everyone’s attention to the table during creation and play. This last one I cannot emphasize enough.” I’m probably going to use it for this, almost as much as the rest!
