SERVER, TERMINAL, NETWORK SYSTEM, PROGRAM AND INFORMATION STORAGE MEDIUM

A server is connected to a terminal via a network, and manages registration of game information, the terminal performing a first game process that utilizes stored game information, and a second game process that utilizes registered game information. The server stores terminal identification information of the terminal and an allowable registration count of the terminal in a linked manner, updates the allowable registration count while being linked to the terminal identification information corresponding to a received update allowable registration count, transmits a registration permission notification to the terminal upon reception of a game information registration request from the terminal when the allowable registration count is equal to or larger than a given number, transmits a registration non-permission notification to the terminal when the allowable registration count is less than the given number, and decrements the allowable registration count when the server has transmitted the registration permission notification to the terminal.
