"Game designers, particularly video and computer games, benefit from integration of flow principles into gameplay design."<p>Gamers will get into zones, similar to athletes, where their reaction times become ultra quick and reflexes are super sharp. Game designers sometimes try to bake these directly into the game, and it's arguable whether or not it's beneficial. For example, many people complain about the killstreak rewards in Modern Warfare 2; once you get going, you're pretty much indestructible.
