I can't see it taking off personally, it's been done before, Onlive were the first I believe (with a viable working product anyway) and they folded, I believe Sony bought their IP which was later rolled into/incorporated into PlayStation Now and never seen again. Though that was a pure subscription service with a flat cost per month for access to the whole library, think Netflix style. With Stadia you have to buy the frontier edition starter pack (you can buy seperately though it will cost you more for the 2 req'd products) and then there is a subscription on top of that for $9.99 a month + you still have to pay the cost of the games, this doesn't seem to be much cheaper in the long run than buying a console and the games outright. And of course you have the beenefit of "owning" the games or at least the physical disks. What happens if Stadi doesn't succeed? can you transfer the game licenses you have purchased to another platform? seems extremely unlikely, so I can't really see any benefit in this service compared to owning a console or a gaming PC.
