Yeah, I actually played Google's augmented reality game "Ingress" for about a year when it first came out a couple years ago and I got really obsessive with that too. I was spending hours a day driving, biking and walking all over the place to capture and link portals. I finally had to quit because I would wake up at night thinking about it and obsessed way to much. It was a LOT of fun, but it was taking over my life and my thought life. I'm just not made to play these games in a healthy way, if there is one. :P
