Game system

Abstract

A running model whose running ability changes in accordance with a given environment is caused to run on a field. The field includes two types of tracks ( 12, 13 ), and hence the running model runs differently on the tracks ( 12, 13 ) depending on the current running ability, thereby providing the running model with variable factors of the running ability.
