"Unlike print, radio, television, or movies, video games are an interactive format that allows them to affect people differently than more traditional forms of broadcast media. Ian Bogost, a professor of media studies at the Georgia Institute of Technology, has argued that the interactive nature of video games makes them an inherently persuasive medium—a system of “procedural rhetoric” that encourages players to create abstract mental models for how systems work and to form judgments about those systems through the act of playing. The design of a game’s models and systems of interactions are intentional choices by the designers, and they set the terms for how a person encounters the game. One video game designer called this effort to induce a certain type of player reaction “emotion engineering” in the design process."

"Research has demonstrated that some game design choices improve the way people focus and increase feelings of well-being. Other design choices can trigger addictive behavior. While research is ongoing, experimental studies have shown that some military FPS games can cause players to become measurably more militarist in outlook. In a “realistic” military FPS game, the presence or absence of rules of engagement, for example, will dramatically change how the player approaches a mission. When the military itself consults on the design of such a game, this leads to a number of uncomfortable questions about why those choices were made."
