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.

couple of aspects

Having actions whose effects are deterministically determined and other influences on the game state, e.g. other players' actions, are relatively

, because the consequences of the actions are at least somewhat predictable, and the number of possible outcomes grows exponentially the further in game time the players plan ahead.

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 the more difficult the values of the actions are to judge, the more likely Analysis Paralysis is to occur. The likelihood can also be modulated by Irreversible Actions, as well as Predefined Goals in games where the players have Perfect Information and Symmetric Information about the discrete game states. This allows the players to plan the consequences of their current and future actions. Irreversible Actions guarantee that consequences of the chosen action will be effective also in the future, and this makes it possible to plan several actions ahead while at the same time decreasing the chances to perform Experimenting. 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, as are open Discard Piles in card games, which allow the players to have Game State Overviews and may cause Analysis Paralysis.

It is possible to lessen the possibility for Analysis Paralysis by introducing Randomness to the consequences of the actions and thereby giving players Limited Foresight and Limited Planning Abilities.

Diegetic Aspects

Consequences

Analysis Paralysis is caused by Stimulated Planning and Cognitive Immersion, and is usually a feature game designers try to avoid. That players have Analysis Paralysis can be a sign that the game does not have the Right Level of Complexity for those players.

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.

The negative effects of Analysis Paralysis for other players can easily be avoided by having Time Limits.
