That's really interesting. Different people have different responses to video games. Personally, I'm aware that my relationship to them is potentially quite unhealthy. I get addicted to things easily, and so I'm careful to not take drugs and to drink only in extreme moderation. Likewise, I'm careful to play games which have definite and regular break points along the way, which push me out of the fantasy and let me do something else for a change.
When I was really into Elder Scrolls games, I would end up going for a walk with my virtual body and making sure it was well rested and well fed, while not doing those things with my physical body. I didn't like that experience and don't really want to repeat it.
