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.

A data exchange system for exchanging object data for first and second game objects having different values, the data exchange system comprising:

a first game apparatus comprising first communication circuitry, first storage, and a first processor;
and
a second game apparatus comprising second communication circuitry, second storage, and a second processor, wherein
the first processor is configured to control to transmit, to the second game apparatus, via the first communication circuitry, first object data for the first game object;
and control to receive, from the second game apparatus, via the first communication circuitry, second object data for the second game object;
the second processor is configured to control to transmit, to the first game apparatus, via the second communication circuitry, the second object data;
and control to receive, from the first game apparatus, via the second communication circuitry, the first object data;
each of the first processor and the second processor is configured to compare the values of the first and second game objects;
the first processor is configured to control to transmit, to the second game apparatus, a first writing start notification for providing notification of a start of writing to the first storage by the first game apparatus of second identification information for identifying the second object data for use by the first game apparatus;
the second processor is configured to control to transmit, to the first game apparatus, a second writing start notification for providing notification of a start of writing to the second storage by the second game apparatus of first identification information for identifying the first object data for use by the second game apparatus;
the first processor is configured to, based on determining by the comparing that the value of the second game object is less than the value of the first game object, control to start writing the second identification information to the first storage without receiving the second writing start notification from the second apparatus so that the writing of the second identification information to the first storage is completed before writing of the first identification information to the second storage is completed, thereby reducing a time period during which the first game object can be illicitly duplicated in the first and second storages;
and, based on determining by the comparing that the value of the second game object is greater than the value of the first game object, control to start writing the second identification information to the first storage when the second writing start notification is received from the second game apparatus so that the writing of the first identification information to the second storage is completed before the writing of the second identification information to she first storage is completed, thereby reducing a time period during which the second game object can be illicitly duplicated in the first and second storages;
and
the second processor is configured to, based on determining by the comparing that the value of the second game object is less than the value of the first game object, control to start writing the first identification information to the second storage when the first writing start notification is received from the first game apparatus so that the writing of the second identification information to the first storage is completed before the writing of the first identification information to the second storage is completed, thereby reducing a time period during which the first game object can be illicitly duplicated in the first and second storages;
and, based on determining by the comparing that the value of the second game object is greater than the value of the first game object, control to start writing the first identification information to the second storage without receiving the first writing start notification from the first game apparatus so that the writing of the first identification information to the second storage is completed before the writing of the second identification information to the first storage, thereby reducing a time period during which the second game object can be illicitly duplicated in the first and second storages.
