“In this study, 103 young adults were given a frustration task and then randomized to play no game, a non-violent game, a violent game with good versus evil theme, or a violent game in which they played ‘the bad guy.’ The results suggest that violent games reduce depression and hostile feelings in players through mood management,”

“It probably won’t come to a surprise to gamers that playing games may reduce stress,” Ferguson said, “although others have been skeptical of this idea. This is the first study that explores this idea, however. It does seem that playing violent games may help reduce stress and make people less depressed and hostile.”
