Abstract: Based on first data corresponding to at least one of a motion and an orientation of a first game controller and second data corresponding to at least one of a motion and an orientation of a second game controller, it is determined whether or not the first game controller and the second game controller are attached to an attachment, and based on the result of the determination, game processing is performed.

Abstract: An example system includes: a plurality of information processing devices each having a game processing unit for performing processing involved in a game, a reproduction data generating unit for generating reproduction data to be used for reproducing game play, a relevant information accepting unit for accepting input of relevant information concerning the reproduction data, and a post transmitting unit for transmitting reproduction data and relevant information; and a server machine having a post receiving unit for receiving reproduction data and relevant information transmitted from the information processing device, a storage unit for storing reproduction data and relevant information in association with each other, and a relevant information transmitting unit for transmitting relevant information stored in the storage unit to the information processing device.

Abstract: An example system includes: a server machine having a storage unit for storing reproduction data involved in reproduction of game play and a data transmitting unit for transmitting reproduction data stored in the storage unit; and an information processing device having a data receiving unit for receiving reproduction data transmitted by the server machine, a reproduction processing unit for displaying reproduction of game play at a display unit in response to reproduction data received by the data receiving unit, a character display processing unit for displaying one or a plurality of character objects at the display unit during reproduction of game play by the reproduction processing unit, and a character action processing unit for causing a character object displayed by the character display processing unit to take a predetermined action with reproduction of game play by the reproduction processing unit.
