Abstract: A display control section displays, on a game screen, a whole or a part of a game space in which a plurality of objects are located. An update section updates a location state of the plurality of objects. A notification subject situation saving section stores, as a notification subject situation, a location state of the plurality of objects at a given time point in a notification subject situation storage. A notification control section executes notification output based on a result of comparison between the location state of the plurality of objects and the notification subject situation.

Abstract: A game configured such that one or more game characters behave based on behavior control data is executed. A reexecution section reexecutes the game from a situation at a time point in the past. A generation section generates second behavior control data based on first behavior control data used at the time point in the past and an operation of a user. A save section causes the situation at the time point in the past and the second behavior control data to be stored as a reference situation and special behavior control data associated with the reference situation, respectively. In a case where a comparison result between the situation of the game and the reference situation is a predetermined result, behavior control section starts behavior control of the one or more game characters based on the special behavior control data associated with the reference situation.
