From the mind of Dr. Timothy Leary comes Mind Mirror, a trippy journey through your own mind. Mind Mirror is not just a game, it is a valuable tool to help you explore your own mind, make decisions, and to envision your ideal self. Play it by yourself or with a group of people.
I absolutely recommend anyone with even a slight interest in psychotherapy to try this game out, not because it'll blow your mind or because Leary was some kind of genius, but because it's a solid example of what I believe to be a therapy-oriented game.
