(Over)hype is bad, indeed because its flip side is disappointment and rage as we have seen so often here and with other games.Yet hype seems to be what drives player engagements, which in turn makes products sell more and gives reasons for the developer to add more content to a game.
As for "story", I've seen some parts and reviews of Starfield which was enough to put me off. Bethesda's modern storytelling is allergic to player agency and the feature NPC characters feel just about as sentient as Elite's concourse crowds.
Also about the streaming platform stuff, you can scuff at viewer metrics for streaming platforms but that's an indicator of players taking a deeper interest in the game or looking for reasons to come back.
Having expectations and judging speculations on the light and more ironic side is much more joyful. Luckily, the majority in this forum tends to see it like that.
