+Rob Conley's (Bat in the Attic) Majestic Wilderlands setting. In our current campaign, we are using D&D 5e. I have also been playing Ben Monday, a history teacher turned supernatural sleuth, in +Tim Shorts' (Gothridge Manor) Wednesday night game, using The Esoterrorists as our rule set.
+Douglas Cole (Gaming Ballistic) has an excellent blog post, Majestic Wilderlands--Do You Hear People Sing?, summarizing our last session. Rob has some interesting posts about his use of feudalism in his setting. As a player, you have to know your station and who you are talking to. It is one my favorite aspects of playing in Rob's setting. Here are links to Rob's posts:
