Big tech already controls the distribution of traditional platforms so they are building AI platforms to make sure they keep control of the distribution of new forms of content, including that for AI games now that they're easier to make than a YouTube video.
But inevitably these products (and the competitors they will inevitably spawn) put us closer to a future of arguably dystopian, AI-driven hyper-entertainment world, even if no one inside the companies meant to do that. I can only hope in that future many people still appreciate human-made games, and even on these AI platforms genuine human ideas (assisted by AI) can still bubble to the top.
As for game quality, these look close to Opus 5.5 one-shots to me, maybe even a little worse.
