A Netflix style streaming service for games that encompasses every video game that has ever existed and works on any device you want sounds absolutely awesome to me... If it worked properly. And by "work properly" I mean to the point that you couldn't noticeably tell the difference between playing it off of your Hard drive or via the streaming service.
This is something I would seriously be interested in and would definitely pay a subscription fee for. Again, If it worked, and if I could access the entire game library whenever I wanted and for as long as I wanted.
Sounds a hell of a lot better than the bullshit system consoles have now of "Buy these games for THIS console and ONLY this console and build your entire library up again when the new one comes out because backwards compatibility is too hard!"
