How to Be a GURPS GM: Counting Heads

This roleplaying supplement offers advice for adapting a campaign to the number of players available. It covers one-on-one campaigns, having each player control multiple characters, and using NPCs or GM-controlled characters when the group is small. For larger groups, it discusses setting limits, managing many players, and adding another GM. It also addresses rescaling adventures and handling attendance that changes from session to session.
