Same here, although 90% of the time, actually playing the game in question quickly reminds me why I am not much of a gamer anymore, either. And I used to be really passionate about gaming... Not sure if it's the games or if I just burned out / got too old for that shit. I've still got a reasonably competent pc right now. Is it worth it to keep the thing up to date for the 10% of games actually still able to keep my interest for a few hours? I don't know. Apart from gaming, a Pentium 4 would probably still do everything I need from a computer right now.
As for E:D, I really was intrigued by the concept, but read bad things about the effects of their decision to go with a p2p network architecture. And SC? I'm a backer, but by now it has become obvious that my rig isn't going to handle the game if/when it's released.
