This paper, which compared and contrasted the various characteristics of the Qin empire in two computer games, tried to find the connection between the empire’s ruling ideology and its multi-aspect effects displayed in turn-based strategy games. With a closer look at Strategy games, readers may find how Qin’s ruling ideology- the legalism that emphasizes “agriculture and war” was a powerful engine for Qin’s conquering performance in both history and strategy games. Besides specific features in the games, readers may also find the interaction between players and their virtual empire echoes the sense of “oneness” within the legalist political blueprint.
