When a player takes certain kinds of actions (or moves), information about the world is revealed. This information can be decided or discovered. When the outcome is decided, that means the player has created a new situation in the imaginary world. For instance, if a yes-and rule is being used, each new statement becomes an accepted new part of the narrative. Some games might provide the players with resources that allow them to decide things, such as having an NPC contact. When the outcome is discovered, that means there is some prior information that is revealed. For instance, walking into a room in a dungeon reveals the contents the GM has already placed there. Interrogating an NPC might reveal clues that are part of the scenario. In a traditional RPG format, most player actions discover, not decide, most parts of the game. In a game in which narrative privileges are distributed among the players, most actions might instead decide events. Some games have a hybrid approach. For instance, in Cortex, players interact with elements that already put in place by the GM, but can also create resources and assets through their actions, such as creating a fire or having a friendly character appear. One common feature of modern storytelling games is that most player actions discover, rather than decide. However, the ability to decide may be imparted by various traits, such as resources, contacts, lucky, and so forth.
