Not gonna use any streaming service anytime soon, my internet sucks and still will in the foreseeable future.
While I like good image/sound quality and would try to get the best gaming experience for my money, I'm not a Hi Fi fetishist and wouldn't spend thousands of bucks a year just to be at the forefront of technology, but if streaming quality is significantly worse in my eyes than on a traditional box, then it'd be a no-go for me. Not even talking about stuff like a sudden drop in image quality or even a pause in gameplay, lol, which obviously happens on Netflix with shitty internet.
But the worst part though is, not owning anything, they choose what's available, at what time and for how long. When a game is gone, it's gone. And what if you can't afford to pay for the pile of monthly fees anymore, well you lose access to all your games, just like that. If I can't afford to buy new physical (or digital) games, I just sit back and take something out of my backlog/collection.
I'm sure streaming is the future, but I won't be using it for as long as there are enough alternatives. I welcome it as an alternative to play games, but I'm not gonna support it, even less so if it's a google service.
