I know Skyrim from reputation of course, though I never played it.
At least you spared yourself the disappointment.
If there is comparison to be made, it's probably Dragon Age: Origins - a big budget cRPG production making a niche genre approachable to a wider audience.
I almost had to get into an argument on another forum when I attempted to explain to a guy in denial why BG3 was in fact A LOT closer to Dragon Age Origin than it ever was to BG2 in almost every single part of its core design and structure.
