Here's the thing though: Skyrim is an anomaly. Dev companies don't care if you're still playing their games after you buy them. It was Bethesda's biggest launch ever, and that's all they care about because just having players play the game doesn't make them money.
It's a sad pattern, but eventually all aging game dev studios take this path. They need a big launch. They don't need continued patronage from their players.
Also, I've only ever heard that starfield is a buggy mess with ironically limited gameplay options for the scope of the universe it's in, and the philosophy the studio took of "yeah not everything is supposed to be interesting, there's plenty of empty space" seems a lot like shooting themselves in the foot.
Well, yeah. I just imagine, especially the Bethesda of today would want to have another title they can milk for another decade.
But yes, they'd need the Bethesda from 12 years ago + 12 years of persistent improvement, to actually deliver something milkable.
This deserves an entirely separate rant, but to me, this already starts at the title, "Starfield". It sounds like Astronomy Simulator 2024. Like no one had a vision other than "Fallout in Space". And that would already have more of a premise than "Starfield" tells me.
