"Google should have launched a new PC game store that lets you download your games. For a nominal monthly fee, you can stream those games from Google's servers instead of needing to buy expensive gaming hardware."

Nvidia already has a product like that called Geforce Now. Instead of having it's own store it integrates with Steam and GOG.

There's still the problem that is a hypothetical customer wants to game enough to pay for Stadia but doesn't have the funds for a gaming PC... why don't they just buy the $300 dollar Xbox Series S?
