Death. That thing you think can only happen to NPCs...yeah, it can happen to PCs, too.
Failure. It's always an option.
Roleplaying. When you pretend to be your character and act accordingly.
Story. What happens at the table when the referee's prep, player choices, and the dice come together.
Yes, And. The thing you think only applies to the referee but it also applies to you.
Collaboration. When the players and the referee work together to create the experience at the table. It's not collaboration if the referee is railroading, nor is it collaboration if the players refuse to engage with the referee's prep.
Sportsmanship. The opposite of being a sore loser. If you get mad when the dice roll bad, if you get mad when things don't go your way, if you get mad when the referee says no, that's being a sore loser, i.e. bad sportsmanship.
Obstacles. The things standing between your PC and what they want. They make the game and story more interesting.
