Information processing system, one or more non-transitory computer-readable storage media, and computer-implemented method

One or more non-transitory computer-readable storage media having stored therein a game application program in which a host device and one or more guest devices participate, the game application program, when executed, causing one or more processors of the host device to perform operations comprising:

• generating a game image by executing game processing based on operation data of the host device and the guest devices, wherein the generating the game image comprises generating the game image by one of a first method of individually generating a game image for the host device and a game image for each of the one or more guest devices or a second method of generating a game image common to the host device and the one or more guest devices;
• specifying whether the game image is generated by the first method or the second method to a system program of the host device;
• and
• instructing the system program to transmit the generated game image to the one or more guest devices with a common command regardless of whether the game image is generated by the first method or the second method.

An information processing system comprising:

• a host device;
• one or more guest devices;
• and a server,
• the host device comprising one or more processors and one or more memories storing instructions that, when executed, cause the one or more processors to perform first operations comprising:
• acquiring operation data from the one or more guest devices;
• generating a game image by executing game processing based on operation data of the host device and the acquired operation data of the one or more guest devices;
• displaying the generated game image on a display of the host device;
• and
• transmitting the generated game image to the one or more guest devices,
• the one or more guest devices each comprising one or more processors and one or more memories storing instructions that, when executed, cause the one or more processors to perform second operations comprising:
• transmitting operation data of the guest device to the host device;
• receiving the game image from the host device;
• and
• displaying the received game image on a display of the guest device, wherein
• the transmitting the generated game image comprises performing switching to transmitting the game image to the guest device using peer-to-peer communication when the number of the guest devices is a specified number or less, and to transmitting the game image to the guest device via the server when the number of the guest devices exceeds the specified number.

An information processing system comprising:

• a host device;
• one or more guest devices;
• and a server,
• the host device comprising one or more processors and one or more memories storing instructions that, when executed, cause the one or more processors to perform first operations comprising:
• acquiring operation data from the one or more guest devices;
• generating a game image by executing game processing based on operation data of the host device and the operation data acquired from the one or more guest devices by peer-to-peer communication;
• and
• displaying the generated game image on a display of the host device and transmitting the generated game image to the one or more guest devices via the server,
• the one or more guest devices each comprising one or more processors and one or more memories storing instructions that, when executed, cause the one or more processors to perform second operations comprising:
• transmitting operation data of the guest device to the host device using peer-to-peer communication;
• receiving the game image via the server;
• and
• displaying the received game image on a display of the guest device.

A computer-implemented method executed by computers of an information processing system comprising a host device, one or more guest devices, and a server, the method comprising:

• acquiring, by the host device, operation data from the one or more guest devices;
• generating, by the host device, a game image by executing game processing based on operation data of the host device and the acquired operation data of the one or more guest devices;
• displaying, by the host device, the generated game image on a display of the host device;
• transmitting, by the host device, the generated game image to the one or more guest devices;
• transmitting, by the one or more guest devices, operation data of the guest device to the host device;
• receiving, by the one or more guest devices, the game image from the host device;
• and
• displaying, by the one or more guest devices, the received game image on a display of the guest device, wherein
• in the generating the game image, a first method of individually generating a game image for the host device and a game image for each of the one or more guest devices, or a second method of generating a game image common to the host device and the one or more guest devices is selectively executed by the host device,
• when the first method is executed, the transmitting the generated game image comprises transmitting the respective game images for the respective guest devices to the respective guest devices using peer-to-peer communication,
• when the second method is executed, the transmitting the generated game image comprises transmitting the common game image to the server at least when a specified condition is satisfied, and
• the common game image received from the host device is distributed to each of the one or more guest devices by the server.
