Perhaps a conventional sport like ping pong or tennis will get you some of the same kicks as wow and help you loose weight.

You don't hear about people being addicted to physical sport much, I'd like to know why.

I'm not personally interested in sport or computer games, I generally seek harmony and equality in my interactions with others so dislike competition and domination ( I imagine such preferences are largely genetic).

War games do scare me more than most sports when there is realistic simulation of killing other people, the less a game resembles real killing the better I think it probably is for people, but this may be unfair.

Keep using that self-insight and ability to think critically about yourself and my guess is you 'll be fine.
