Bullets are trying to get me out of cover. Explosions penetrate my field of vision, blood covers the floor and somebody yells instructions over the intercom. Welcome to the modern world of gaming. Gone are the days of endless sessions of Tetris and hours of Link discovering the pixel-loaded world of Hyrule. High definition graphics brought around a wave of realism, which flesh out the colorful world of gaming. More and more do gaming worlds mimic and imitate or even match environments found in reality. Virtual environments are not only a necessary narrative device for games; they also challenge the brains of players in interesting ways.
