Maybe I'm old fashioned....
But I also like having my games available to play off line as well as on line. There's nothing more irritating than not being able to play games you have legitimately purchased, because your PC/Console/ whatever can't connect to the network.
A case in point, the recent Playstation Leap year fiasco. I couldn't play Darksiders, even tho this was a game I had bought from the shops, not downloaded, so I had the physical media for the console, but because of the trophy system, the game got halfway through loading and then dumped me back out because it couldn't sync it over the network.
It all boils down to control at the end of the day, and I think when Gaming finally does move away from home PCs and consoles, then I shall find something else to do with my time. Hell I'll be an old fart by then anyway so I can sit at home in a rocking chair moaning about the good old days, and all the cash I save from not buying games any more I can keep under my mattress.
