Abstract

Game program has a procedure for determining item price (IVD), for respectively computing price for transfer of a plurality of items to be used in a game every each item, and a procedure for executing the procedure for determining item price when possession state of the item is likely to be changed in the game, and the procedure for determining item price has a procedure for computing price for transfer of the item on the basis of individual data concerning each item and for displaying the computed price. The price for transfer of the item is determined and shown, changed by the individual data concerning each item, so that the player can buy or sell the item with reality similar to economical activities in the actual world.
