Sorry, my definitions got cut off.
Powergaming is when a player forces impossible/unrealistic situations on another player which makes it impossible for the affected player to respond. For example, if a player were to have a broken leg but was suddenly able to easily jump across a ravine, this would be unrealistic because the player is injured.
Metagaming is when a player uses information gained out of character to give their actual character an advantage. For example, if a player reads in the chat or discord that there is an event happening and then the player heads to this event, they are metagaming because the player’s character had no knowledge of this until they learned outside information.
