Analysis Paralysis

When gameplay seems to draw to a halt due to one or more players need to spend considerable amount of time planning or understanding the consequences of different possible actions.

Players can spend considerable amounts of time planning their actions in some games. When this makes other players have to wait since gameplay cannot continue until the player has made up his or her mind, it is usually experienced as negative and referred to as Analysis Paralysis. The reason for Analysis Paralysis may be that the number of choices is overwhelming so one does know where to start ones planning but may also be that one most of the time can see the advantage of just a bit more planning.

Examples

Chess and Go have been used as prime examples of games where there is a possibility to almost endlessly analyze possible future actions. Both have decision trees, which grow exponentially over game time.

Diplomacy, even though the possible actions are quite limited, can cause Analysis Paralysis when the players start to think recursively about what the other players are trying to do and how the other players would perceive the players' actions.

Using the pattern

Analysis Paralysis is a negative pattern in the sense that avoiding to have it unintentionally in a game is more often a design goal than intentionally having it present. Ricochet Robots is however an example where the pattern is not a problem since all players are causing the time-bound Analysis Paralysis and one player's action forces all other players to reconsider their plans.

Although this may occur in any game where a player has a choice and the game state is frozen until the choice is made, there are some design choices that can increase the likelihood of the pattern emerging. Analysis Paralysis can be achieved by letting players have Freedom of Choice between several actions with Predictable Consequences, even if these are Limited Set of Actions or players have Limited Resources. This forces players to consider Tradeoffs and if the value of the effects caused are difficult to judge it may further increase the risk of Analysis Paralysis occurring. Budgeted Action Points provide means of expanding the number of decisions the players have to make in each decision point, in effect, broadening the scope of Freedom of Choice.

The amount of information available to players can easily affect the presence of Analysis Paralysis. Perfect Information lets players have more information available for consideration while Symmetric Information helps players consider other players potential actions into the planning. Open Discard Piles in card games, giving players more complete Game State Overviews, allows players to easier calculate odds for future draws and plays of cards and may thereby also cause Analysis Paralysis.

The likelihood can also be modulated by Irreversible Events and Limited Set of Actions of other players. This allows players to a greater degree to not only to consider the direct effects of their actions but plan a sequence of actions. Predefined Goals may affect the likelihood of Analysis Paralysis occurring differently depending on how distant the goal is: goals that may easily be reached may lessen it as may distant or strategic goals while the ones in between may increase it.

There are several ways of reducing the risk for Analysis Paralysis. First Real-Time Games and Time Limits makes it impossible to maintain the Analysis Paralysis for longer than a certain period of time, but at the potential cost of introducing Time Pressure. One can also introduce Randomness to the consequences of actions and thereby giving players Limited Foresight and Limited Planning Abilities. Games with Private Game Spaces (e.g. Puerto Rico or Race for the Galaxy) can mitigate the causes of the pattern since other players can easier plan simultaneously plan when their actions do to a lesser degree affect each other.

Consequences

Analysis Paralysis usually a feature game designers try to avoid in Multiplayer Games. That players have Analysis Paralysis can be a sign that the game does not have the Right Level of Complexity for those players but can also indicate a desire in the design to have Stimulated Planning and Cognitive Immersion.

In games with Turn Taking, the presence of Analysis Paralysis leads to excessive Downtime for the other players in case some of the players get stuck in planning their turns. The nature of Analysis Paralysis situations has a somewhat adverse effect on the Anticipation of the uncertain outcome during the play.
