for the parts that got cut off with power gaming and metagaming.
What is Metagaming?: This is when your character uses or refers to information that there is no way they'd know. Ex: One of your characters is just a poor peasant and yet is aware of a coup forming that most other players have heard nothing about because you have another character who is involved in the plot to start the coup.
What is Powergaming?: When you try to force an outcome on another player’s character OR your character is unrealistically strong or proficient in a certain skill. Ex: "Bill pierces Bob's heart with his arrow" OR Bill is just a farmer with no background in magic and yet can he can summon the dead somehow.
