Happy International Game Master’s Day! Without folks willing to sit “behind the screen,” there wouldn’t be much of a hobby, so today I’d like to extend a heartfelt “thank you” to every GM out there who’s put in time and creative effort to help groups play roleplaying games. I’m especially grateful for all the GMs who helped me discover this hobby and grow as a game master, including A.P. Klosky and the Elders of the Wittenberg Roleplaying Guild.

To celebrate, I’ve compiled some of my favorite articles I’ve written on the topic of gamemastering. You can also check out some of my recommended books for GMs that are part of the GM’s Day sale going on today at DriveThruRPG.

March Fourth for GM’s Day! Today’s the day to tell your GM how much you appreciate all that they do. And if you’re the GM, today’s a great day to treat yourself to a little something to help “fill the well.” DriveThruRPG is having a huge sale on a ton of PDFs and ebooks to help you run a better roleplaying game. What follows are some of my favorite game master resources that are currently free or discounted.
