Stuart at Strange Magic has posted GM Badges, designed to tell potential players about your games. It looks like a fun idea, so here's what I came up with about my games. Keep in mind, there are categories I'm not including here, as I've used multiple techniques from the selections and they would conflict with each other.
The idea here is to display for potential players what type of games you like to run...or conversely for players to show which games they enjoy playing.
I'm sure everyone's experiences in my games differ and aren't completely represented here. However, if I think upon my best run games and those games that I enjoyed the most, this is the list that is most representative.
Interestingly, The Warlock's Homebrew has posted a Players version of these badges.
It's all in fun and just a short bout of thinking.
