Abstract: An example game apparatus selects an operational character that is to be used by a player in a multiplayer game with competition. The game apparatus selects an additional character that is to be added to the operational character from a plurality of candidates for an additional character to be selected. The additional character is associated with an image of the additional character, information of an effect to be given to performance in the game with competition of the operational character to which the additional character is added, and information about a type. The game apparatus generates a selection image including at least an image of the operational character selected by the player and each other user, an image of the additional character selected by the player, and an image of the type of the additional character, for display, during selection of the operational character and the additional character.

Abstract: An example game apparatus executes an opponent information screen process of generating an image of an opponent information screen showing an opponent character and an opponent additional character, and executes a player information screen process of generating an image of a player information screen showing a player character and an additional character selected as an own additional character added to the player character according to an operational input. The image of the opponent information screen contains an opponent character image of the opponent character, an opponent additional character image of the opponent additional character, an own icon image, and an own type icon image. The image of the player information screen contains a player character image of the player character, an own additional character image of the selected own additional character, the own type icon image, an opponent icon image, and an opponent type icon image.

Abstract: An example information processing device chooses a subset of game objects as candidate game objects from among available game objects; selects a candidate game object as a selected game object according to the user's instruction; updating, when an update condition is satisfied, possession data in the memory so that the selected game object is set as a possessed game object possessed by the user; on a condition that the remaining time has been expired, replacing the candidate game object on the selection screen with a game object newly chosen from among the available game objects; and on at least one of a first condition that the candidate game object has been selected as a selected game object and a second condition that the update condition is satisfied, replacing the selected game object with a game object newly chosen from among the available game objects.

Abstract: A ranking of each of a plurality of users is set, and based on a numerical value indicating the ranking, an indicator is calculated such that the smaller the numerical value, the greater a value of the indicator. Then, the indicator calculated for the user is displayed. The indicator is displayed such that the higher the ranking, the greater the value of the indicator. This can enhance the motivation of a user.

The portable terminal establishes wireless connection to the information processing device in accordance with a second procedure different from the first procedure and transmits second operation information representing an input operation onto the portable terminal to the information processing device.

Abstract: In order to attain the object described above, a game apparatus is able to use a touch panel 13 and operation means, executes a shooting game, and positions an aim G3 representing a shooting direction at a predetermined position. When sliding operation is received on the touch panel, the aim G3 is displaced from the predetermined position by a moving distance based on change of a touch position (input coordinate position). Shooting is virtually performed in a direction based on the position of the aim according to an operation on the operation means.

Abstract: A game apparatus includes a CPU, and the CPU sets a weapon to be transmittable according to an instruction by a player. More specifically, a seed is generated from a weapon, and transmittable seed data corresponding to the generated seed is stored in a memory for saved data. When a game apparatus is carried in a sleep state by a player, it makes a communication with another game apparatus to thereby transmit and receive the transmittable seed data with the other game apparatus. Accordingly, the transmittable and receivable seed data, that is, the seeds are exchanged. During the game, the received two seeds are fused to thereby generate a weapon.
