For many players, games are entertainment, diversion, relaxation, fantasy. But what if certain games were something more than this, providing not only outlets for entertainment but a means for creative expression, instruments for conceptual thinking, or tools for social change? In Critical Play, artist and game designer Mary Flanagan examines alternative games — games that challenge the accepted norms embedded within the gaming industry — and argues that games designed by artists and activists are reshaping everyday game culture. Flanagan provides a lively historical context for critical play through twentieth-century art movements, connecting subversive game design to subversive art: her examples of “playing house” include Dadaist puppet shows and The Sims. She looks at artists’ alternative computer-based games and explores games for change, considering the way activist concerns — including worldwide poverty and AIDS — can be incorporated into game design. Arguing that this kind of conscious practice — which now constitutes the avant-garde of the computer game medium — can inspire new working methods for designers, Flanagan offers a model for designing that will encourage the subversion of popular gaming tropes through new styles of game making, and proposes a theory of alternate game design that focuses on the reworking of contemporary popular game practices.
