The engineering side did a great job on a complex technical task. It's satisfactory, kind of works, not great, not terrible.
What boggles the mind is that nobody is able to formulate who is Stadia even meant for. Who are the target customers?
Draw a Venn diagram of people who:
- care about gaming
- are OK paying full price for their games
- are OK paying 10 euros a month subscription
- are OK buying an extra controller
- have top-notch, 100% reliable internet connection
- are willing to accept occasional technical glitches
- are OK with Google's mercurial approach to product lifecycles
but do not:
- have a computer
- have a console
- have a Steam library
- mod their games
- subscribe to Nvidia's cloud gaming service
Just giving some off-hand estimates, my estimate is 0.00015% of the world's population meets these criteria. The only reasonable business model must be "people will want to try it out and then forget to cancel their subscription".
