This post is part of a series of posts on foundations of game mastering. First post in the series can be found here, and next one here. As usual, if you are confused about any terms, make sure to check out the glossary. Finally, we can talk about the core thing a GM has to think about - fun. By “fun” I mean any kind of enjoyment that is had by people at the table. We will start with the kinds of fun that is had by everyone, then kinds that are had solely by the players (for no other reason than that there are more sources to reference, as this topic is well-studied), and then talk about the kinds that are exclusive to the GM.
