My feeling, that I've learned after many years of doing it wrong, is that 'taking out' your stress with violent or aggressive acts, even virtual ones, isn't a healthy way to deal with it. It reinforces it rather than releasing it. Calming exercises, deep breathing and letting stress go is a much more useful way to deal with it.

In that vein, I recommend Tiny Glade for stress relief. Or any so called 'cosy' game.
