The question how players can be intrinsically motivated to play or keep playing a game is the core of game design. McGonigal argues that players always try to reach the limits of their ability instinctively. During the course of a game, players cease to think and act reasonably compared to real-world practices. Instead, they seem to dive into the virtual world and start to focus on the peculiar reality of the game. This “narrowing of consciousness” is considered to be achievement-oriented motivation.
