Patent ID: 10765941

Abstract:
A non-limiting example communication game system comprises at least two game apparatuses, and the two game apparatuses communicate with each other directly or via an internet according to instructions of a player. At this time, one of the two game apparatuses functions as a parent apparatus and the other of the two game apparatuses functions as a child apparatus. If both players instruct to exchange characters, character data are sent and received between the parent apparatus and the child apparatus. When a rarity of a character X that is to be sent on exchange is lower than a rarity of a character Y that is to be received by exchange, the parent apparatus receives a notification of writing start from the child apparatus, and performs save writing. On the other hand, when a rarity of a character X that is to be sent on exchange is higher than a rarity of a character Y that is to be received by exchange, the parent apparatus transmits a notification of writing start to the child apparatus, and performs save writing.
