<P>PROBLEM TO BE SOLVED: To provide a game service system capable of expecting the prolongation of the contract term of registered players. <P>SOLUTION: Monthly addition points granted to the members per month are increased according to the duration of the contract term of the members and the more the contract term prolonged, the more the monthly addition points are granted per month. As a result, the players tend to renew the contract term by their anticipation of such more monthly addition points. This enables the expectation of the prolonged contract term of the members. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
