Something new and interesting has been dropped into the OSR realm within the last 24 hours or so and is generating some interesting discussion. It is the concept of GM/DM "merrit" badges as a means of giving folks an idea of their DMing style.
The idea appears to have originated over on Strange Magic where a nifty list of icons and meanings for them was posted. (Full list on Strange Magic). I was first made aware of them on Warlock's Homebrew and have since read a different viewpoint over on Dungeons and Digressions.
I'm also of the opinion that while nifty looking and a neat idea, it leaves something not quite settled and potentially more confusing than before. A self evaluation of DMing style will certainly cover some of the bases, but will it tell the whole story?
Giving it some thought and a little nap time allowed the following idea to ease into the cranial dice box. Since none of these seems to fit 100% to any DM all of the time why not use this as a basis for players to evaluate a DM on a rolling basis? Treat it like an alignment chart for the current campaign. Present players with the list and have them grade the game they are in each session or two in each icon category based on their perceptions.
For example by giving each icon category a grade from 1 to 5 with 1 being once in a while to 5 being most of the time. You could get something like this:
