I would make a review thread but it seems like reviewers just started playing, so there aren’t many yet.
They’ve been investing way more in gaming lately, but I imagine their long-term plan involves setting up Apple Arcade as a premium brand for high-end titles in a way that might be undermined by promoting their “competition” now. Like if Apple promoted a lot of shows that were available on iTunes shortly before launching Apple TV+. No idea, though, I’m just wildly speculating.
