Abstract: An exemplary information processing system causes a player character to move in a virtual game space in which a plurality of unit areas are set. The exemplary information processing system changes the states of the unit areas set in the first state to the second state, among the unit areas specified by a predetermined action performed by the player character. The exemplary information processing system updates a first parameter associated with a player, based on the number of the unit areas having been changed from the first state to the second state. The exemplary information processing system updates a second parameter, based on the number of the unit areas having been changed from the first state to the second state according to either the predetermined action performed by the player character, or the predetermined action performed by another player character corresponding to another player different from the player.

Abstract: A player character's action is controlled based on a user's input. A first object associated with the player character is arranged at a position in a virtual space based on the user's input with reference to a position of the player character. In the virtual space, a region having an extent in a horizontal direction set based on a height in the virtual space at which the first object is arranged, the region including a position related to the horizontal direction of the first object, is set as a first region related to the user. The player character's action is controlled such that a predetermined action has a form varying depending on whether or not the player character is located in the first region.

Abstract: In a virtual space, a state of at least one of a first object and a second object that is associated with a first user is changed based on a first user's input. A first region related to the first user is set based on a position of the second object arranged with reference to a position of a first player character. A state of at least one of the first object and a second object that is associated with a second user is changed based on the second user's input. Changing of states of the first and second objects in the first region based on the second user's input is limited.
