At extreme levels of play for a game, I rarely find myself seeing certain notification from the game in my peripheral vision. An extended bout of Mechwarrior left meconstantly glancing down because I thought I saw the flashing red of my mechs armor. After Rome: Total War, I would turn my head to the left because I saw a falling square notifying me that something happened. A similar thing happened after Civ 5, only on my right. Those are the only games that's happened for, though. Normally, the only consequence of playing too many FPS games is a overwhelming need to play a turn based strategy game, or vice versa.
