I want it, but I want the Netflix model. What I don't want is to buy games fullprice on their platform. Let me pay 10 bucks a month for a rich gaming catalog that I can play on anything from Mac, to phone to tablet and I'm going to use it.
Some games lock players in and absorb their time continuously (e.g. Overwatch, PUBG, WoW, etc), while others package a digestible block of content that can be consumed in 10, 20, 50 hours, and then it's done. Subscription payouts based on proportional screen time would drastically favor the former over the latter, while lump-sum compensation flips the tables since it doesn't consider ongoing server and infrastructure costs needed to make multiplayer work.
I think this "Buy your games, and subscribe to them too" model that Stadia is using is how they're trying to split that baby, but given that nearly every other service is either subscription or one-time purchase, I have a hard time seeing it stick around long-term. Then again, some console systems also function that way, so I might be wrong.
For me, I prefer something like Apple Arcade because it downloads the game to my system. I'm not sending commands over a network connection that might flake out at a critical moment. I also don't care about playing with others, usually, though.
