[MEANS FOR SOLVING PROBLEMS] An individual function server adds 1 to the number of uses nx of an item x used at steps S81, adds the number of uses nx of the item x to the total number of uses N of the items in the category to which the item x used belongs at step S82, computes by a predetermined computation the evaluation value of the item x by using the number of uses of the item x and the total number of uses of the items in the category to which the item x belongs at step S83, reduces the ability value (attack power) and parameter of the item x so that the ability value and parameter are within allowable variation ranges of the item x according to the evaluation value of the item x at step S84, and computes the influence of the use of the item x according to the corrected ability value and parameter of the item x on the virtual space.
