A Healthy Release...For Some

I saw an article recently that said playing games is healthy way to relax and that it promotes self esteem. I respectively disagree, at least personally. When I play games, especially competitive ones, the anger and frustration that boils to the surface has become something I am notoriously known for among my friends. Maybe it stems from a overly competitive nature, but when out in contest in something irrelevant like a game I become an aggressive monster. Though, thinking about it, maybe allowing those emotions to be released is a form of expression in itself. I certainly don't react that way to anything else. So, question of the day: how does playing games make you feel?
