<P>PROBLEM TO BE SOLVED: To provide a game system and the like for appropriately controlling the timing to remove the ban on the presentation of multimedia information to be presented to a player within a game. <P>SOLUTION: When a request transmitted from a terminal device 241 is received (301, 311, 321), a server device 221 detects whether multimedia information having an identification name designated in the request is presented to a player before (302, 312, 322). If not presented, the server device 221 determines whether the player proceeds with a game rightly (303, 313). If it is determined that the player proceeds with the game properly (313) or the information is presented to the player before (322), the server device 221 transmits a response designating a decryption key to the terminal device 241 (314, 324). The terminal device 241 decrypts the multimedia information from encrypted information using the obtained decryption key and presents the decrypted information to the player (315, 325). <P>COPYRIGHT: (C)2012,JPO&INPIT |
