Abstract: Movement control of a player character in a field in a virtual space is performed based on a user's operation input. At least one first type of object is disposed in the field. Lightness for the first type of object is set such that the first type of object is visually recognized even when the field is dark. When the player character satisfies a first condition at a location where one of the at least one first type of object is disposed, lighting is set in the virtual space such that a range in the field including the location is lighter than before the first condition is satisfied.

Abstract: An example of an information processing system controls motions of a plurality of non-player characters in a virtual space. The information processing system, based on a predetermined condition, sets each of the plurality of non-player characters in a fightable state for fighting against another non-player character or a player character operated according to an operation input performed by a user. A fighting group in which a plurality of characters including a non-player character in the fightable state participate, is set. For the non-player character participating in the fighting group, another character participating in the fighting group is set as a fight target. Based on the fight target set for the non-player character, a motion, regarding a fight, of the non-player character is controlled.

Abstract: Movement-related parameters used in virtual physical calculation are changed such that a designated object selected based on an operation input is caused to perform return movement to return to previously recorded positions and orientations, sequentially backward from the time of giving a start instruction based on the operation input. A state in a virtual space including a player character, the designated object, and other objects is updated based on the virtual physical calculation.
