I know the feeling Jimmy. I used to be a big time game junky - mostly RPGs as well as some strategy stuff. I've abstained for the longest time but every once in a while a scene from some game flashes across my mind - used to be Age of Empires, Command and Conquer, Baldur's Gate, Settlers and the like for me. I think that it will always be a problem for us but if you play for short spells and take breaks it might be possible to still enjoy some of them.
One of the problems I faced with games is I would immerse myself in them and hold one position for a long time with a repetitive hand movement - no, I'm not talking about my joystick! Besides which I'd find myself tensed up and would have to remind myself to let my shoulders relax. I think that would be the problem regardless of what console you used - now if they could invent something that just responds to thought and eye movement... hmmm.
