A game system provides multiple classifications of character characteristic and is capable of advancing a game by assigning the desired characteristic to a character from multiple characteristics. Two jobs, that is, a main job and a support job are selectable for a character and a fixed pattern of table configuration data is provided as characteristic value information according to the job. In addition, the table configuration data corresponding to the classification of the job is extracted and applied to a growth table for each job, and ability values of the main job and support job are weighted differently so as to achieve character characteristic having two job abilities together. Accordingly, it is possible to effectively increase the job types to be assigned to the character and to create an interesting game, while reducing necessary memory capacity.
