I think that Skyrim was good for it's time and I say this as someone that could never get into Skyrim, I mean even you said in another comment that you've played 400 hours of Skyrim. You don't do that unless there is something enjoyable about the gameplay loop.

But the thing is you can't keep making, re-skinning and releasing the same game you made a decade ago, as much as gamers say they just want companies to remake their favourite games from their adolescence and update the graphics with some quality of life improvements, this isn't what gamers actually want. Such a game would appear very dated on release and get harshly criticised by gamers. Old games always had their flaws that would be very apparent nowadays. And I think that's exactly what's happened with modern open world Bethesda games, ever since Fallout 4 actually. They keep making a similar type of game, and it feels old on arrival, with the same flaws as games from a decade ago.
