Digital games are often considered to be the"ninthart"following such traditional arts as literature, painting,music, etc.However,since the evaluation criteria of the game have been dominated by the commercial system for along time,which hascaused the game creation to be biased at the ideological level,it is necessary for designers to establish a set of artistic evaluation criteria for digital games, so as to promote the artistic creation and theoretical research of games. From the perspective of artistic thought, art philosophy and design innovation, the core artistic factors of the game were discussed through the methods of aesthetic historical literature review, case analysis of game artworks and analysis of art theory. The artistic criteria of the game should include three mainaspects:emotional performance,innovation and artistic reflection.Art emotion was the common character and coreofall arts. Artistic reflection was the sublimation of artistic concept and the motive of artistic creation.Innovation was the driving force for the upgrading and development of arts. The criteria are independent of the commercial system and will promote and guide the development of digital games at the artistic level.
