On Hill Cantons, ckutalik asked GM's to list their three best practices, techniques, or tricks used at the table.
I don't claim to be an exemplary referee. After all, it was only a year ago that I started playing again and discovered the OSR. However, I've found the following techniques help me at the table:
- Always say "yes" to players.
- If the players, in their deliberations at the table, theorize about something more interesting than what you actually planned, drop your plans and use the more interesting idea.
- Never keep the players waiting—not even for 30 seconds—while you look up something in a rule book. Just make a plausible ruling and move on. You can check the rulebook after the session.
