GayGamer.net writes: A mind game can easily be described as playing with your opponent's head to your advantage. It exists in any team activity outside the gaming world as well. Sports involve mind games all the time, but they are called "psyche outs" or simply an act of "deception." But a mind game can be far more hurtful than that. I personally like the potential effects mind games can have on your opponent's psychological health during a match. I mean, if you're playing with someone, why not play with their heads too?
