Great write-up Bul. I agree with you completely.
My wife complains when I get home from work before her and start to play games. As she walks in the door to realize that I'm immersed in a videogame, she groans. I've repeatedly told her that after a long, hard day at work, losing myself in a game is a stress reliever. In fact, no matter how frustrating or hard a game may be, or how easy for that matter, it still relieves the pressure that builds up at work all day. Whether I'm playing Picross DS or MP3 or Illusion of Gaia or Tetris, I'm getting much needed relief.
It is my escape. Some people go to alcohol, others to pornography, and others still to drugs. I go to videogames. Now I know that some may try to use that against me and say that I'm addicted to games (which my wife will agree that I am not addicted to them), but I don't think that it's the same as the other "stress relievers" mentioned before.
I feel that losing your mind into a game can actually benefit you. Much like reading a book stimulates your imagination, playing a game actually puts you into that imaginary world. And while the 2 are not quite the same, they bring the same effect to your mind.
