When X-wing first came out I spent an entire weekend 14hrs+ a day playing it. when I went to bed on sunday and shut my eyes i could literally see and hear the TIE fighters flying round my head, lasers and all. Cool I thought.
quite a few years later, my friends and I played Goldeneye on the N64 for about 2 months solidly, not leaving the flat. When I finally did go out i had to concentrate hard to not start running in open areas, hiding behind walls and wandering where I'd left my AR-33 etc... now that was a bit worrying. Good thing I don't have epileptic predisposition.
note to self : if you play computer games for too long your life can and will morph into a computer game...

dreams are just the start.
