Before play begins, the participants should choose a setting. The setting might be cyberpunk, fantasy, Russian Revolution, ice age, English Civil War, or anything else the players can imagine. The characters and environment made by the players and GM should be consistent with the setting.
With the GM's permission the character concept can be updated or modified. In some cases, a player may petition for such a change. To prevent character development from distracting players from the game, many GMs will only entertain suggestions to modify a character concept at the end of a game session.
The GM will sometimes use (or ask players to use) a random or pseudo-random influence, to help determine the outcome of particular actions. The GM may specify the random factor (GM's whim, tarot cards, question to a passerby, vote, dice, a spinner, random number tables, bribes to the GM, expenditure of chits or points, acting out the scene, rock-paper-scissors, etc.), or allow the player to choose. The GM interprets the result.
