I too, believe it or not, play games to escape from the tough social problems I experience in life. You can't be teased about being a gamer, on a video game. Everyone is in a zone, where we are all somewhat equal.
I also use it to express my feelings to others, as an anonymous person. They then can't tease you too much, or cause problems in your life. They can only give advice.
I also love to enhance and express my imagination through forging. I get to meet new people, and be respected in a community in such I way that may be unlikely in real life.
