So I think I got a good peg on why Phil no longer enjoys or even dislikes playing games. The man, for last 3-5 years, has dropped all things but gaming. He has no social life, no hobbies, no activities, and even no job that takes him outside of this. So, for day in and day out all you do is play games, and play games, and play games. Not only is the redundancy of the activity ruining the experience, but the exposure really makes you start peeling back the meta of the activity. You stop looking at the images presented to you and eventually see the cycle of gameplay you're staring at for hours a day. Once you stop seeing the game, and just see the cycle of it, it really ruins playing a lot of games; add to the fact that is what you do all day and it's just a shit experience.
I've had three months where I had nothing to do but play games for the most part and it went from a fun experience to being utterly disappointing and dull.
If all you do is play games all day long, it's going to be a miserable life and explains so much into how miserable and whiny Phil is.
