Player-Defined Goals

The one-sentence "definition" that should be in italics.

Goals and subgoals that players can create or customize within the game itself. Structured Player Defined Goals are possible by providing mechanics to let players determine the requirements, rewards, and punishments of the goals by having explicit game rules that govern these goals. By specifying the end conditions and evaluation functions within the game as conditions of the game state, these Player Defined Goals can then be monitored by the game system similarly to other goals.

Example: Player Defined Goals are employed in Diplomacy in a way that the players can set their own secret goals and strategies, but the impact of the Player Defined Goals is more evident when some players agree on acting together against another player. However, the goals are only an agreement between the players and they are not explicitly stated in the game mechanics or rules.

Example: SimCity and most of the other Sim -games are good examples of games where Player Defined Goals are possible and also integral to the resulting gameplay. The gameplay is open as there are no winning conditions provided by the game itself and the game system is complex enough to allow huge amounts of different outcomes. The player is free to choose and pursue as a goal almost any possible game state from building the biggest city to making a strong police state to having fun in bulldozing the suburban areas when they are flourishing.

Using the pattern

Games can provide support for defining the Player-Defined Goals so the game system can automatically detect successes and failure as well as applying Penalties or Rewards. However, this is not necessary for Player-Defined Goals to be part of a game design. In fact, players can add their own goals to any game so the pattern can exist in any game, and is for that reason a possible Subjective Pattern in any game. However, it can be encouraged by providing players with information so they can see that certain series of actions and activities can result in specific outcomes and can therefore be potential Player-Defined Goals.

Consequences

Player-Defined Goals let players have Creative Control in games and can add Freedom of Choice regarding which goals are available. The goals defined by players are typically Optional Goals and in many cases also Ephemeral Goals. When defined based on the existence of other players' goals they can inject Preventing Goals into a game and since players can add Rewards or Penalties outside the game system they can also provide Extra-Game Consequences.

One effect of Player-Defined Goals is that they can allow players to have closures in Unwinnable Games. This can in practice let players have winning conditions for a game of their own built upon the game or can simply add structure to what otherwise may be perceived as one long continuous experience without variation.
