This just means that while any individual game is not punished or rewarded by being sucky (regardless of budget), overall GP depends on great quality of content. We saw this with movie streaming services, no one buys streaming service to watch loads of mediocre shows, but a few big ones are pulling it. The moment the service doesn’t provide great content in certain regularity…

This incentive the streaming platform owner to control quality at least for their flagship titles.

All in all, not that much different from existing digital stores (steam) or consoles (ps, Xbox and fight over better flagship title)
