Video game system and storage medium storing video game program

A non-transitory storage medium storing a video game program to be executed by a computer of each of a plurality of video game devices connected together so that the video game devices can communicate with one another, wherein the video game devices display the same virtual game world while being synchronized together, the virtual game world including therein player characters each controlled by one of the video game devices, the video game program causing the computer to perform:

• a object initial information production step to produce object initial information used for introducing an object, different from a subject player character, into the virtual game world and for controlling the object in the virtual game world, in response to a predetermined input operation by the player;
• an object operation controlling step to control the object according to a predetermined rule after introducing the object into the virtual game world based on the object initial information produced by the object initial information production step;
• an object information transmitting step to transmit the object initial information to the other video game devices;
• and
• an object information receiving step to receive the object initial information from one of the other video game devices in response to a predetermined input operation by a player of the one of the other video game devices,
• wherein when the object initial information is received from the one of the other video game devices, the object operation controlling step introduces an object into the virtual game world and then controls the object in the virtual game world according to a predetermined rule executed by the one of the other video game devices after the first video game device introduces the object into the virtual game world, and wherein the predetermined rule at least determines the movement of the object based on an initial object position included in the object initial information.

A method performed using at least a first video device and a second video device communicating with the first video device, wherein each video device displays images of a virtual world being displayed through images on the other video device and the virtual world includes player characters each controlled by one of the video devices;

• the first video device includes:
• a communications unit that exchanges data with the second video device;
• a processor executing a first program stored in a non-transitory memory of the first video device, the first program causes the first video device to:
• generate object initial information to be applied to introduce and initially position an object in the virtual world in response to a predetermined input operation performed by the player on the first video device, wherein the object is different from a first player character;
• control the object according to a predetermined rule after the object is initially positioned the virtual world based on the object initial information;
• and
• transmit the object initial information to the second video device via the communications unit in the first video device;
• and
• the second video device includes:
• a communications unit exchanging data with the first video device;
• a processor executing a second program stored in a non-transitory memory of the second video device, the second program causing the second video device to:
• receive the object initial information from the first video device via the communications unit in the second video device;
• and
• control the object according to the predetermined rule wherein the object is represented and initially positioned in the virtual world based on the object initial information and the predetermined rule determines the movement of the object.

A method to play a video game on video devices communicating with each other to display images of a same virtual game world that includes player characters each controlled by one of the video devices, wherein each video device:

• generates first object initial information to be used to introduce a first virtual object, different from the player character controlled by the video device, into the virtual game world and control the first object in response to a predetermined input operation by the player using the video device;
• control the first object according to a first predetermined rule after introducing the object into the virtual game world based on the first object initial information;
• transmit the first object initial information to another one of the video devices;
• receive a second object initial information generated by another one of the video game devices in response to a predetermined input operation by a player of the another one of the other video devices:
• in response to the reception of the second object initial information introduce a second an object corresponding to the received second object initial information in the virtual game world, and
• moving, in the virtual game world, the second object based on a second predetermined rule.
