Abstract: Among game elements, such as a character and an item, use status of a game element of a specific type or property (comprehensively “specific item”) is monitored. For example, the use status is monitored with respect to various monitoring parameters related to a transaction between users, a fusion, use in a game, or the like, of the game element. Then, when one or more of the monitoring parameters satisfy a predetermined adjustment support condition, an adjustment support control to increase a use quantity of the specific item of a monitoring target is performed. The use quantity of the specific item includes, for example, an available quantity of the specific item in the game or a total number of specific items that can be possessed and acquired by players.
