Anecdotally, nearly all of my friends growing up played violent video games. I did see this behavior from one of my friends and his aggression following losing a video game. But he also had the same reaction after we lost a soccer game as well. I think that video games may show this effect, but it is not necessarily the cause. After all, all of my friends played the same violent video games (often together); the individual was the common factor in the aggressive activity, not the game.
