Commonly, alpha-beta pruning is used in strategy games to help plan a sufficiently efficient (in game terms) path through the various game states. Think of chess, for example, where it is possible for the AI to create a look-ahead of every potential board state from one position to another. This is a waste of resources; alpha-beta pruning can reduce this by discarding those that are less efficient or actively wasteful. This could be used in almost any genre where there is the possibility that a path through the various game states can be abstracted as a series of intermediate states.

Truly lifelike behavior might need the addition of a few more ingredients, but we are moving in the right direction.
