I have been playing for years even before the steam release and feel in love with the world created in the game. The plot, lore and characters keep me immersed in Savarra while i have caught myself in many runs trying to midmax builds, whether that was for combat or the most effecient way to make my PC a thicc baddie lol (this was before you could ajust your PC's figure). Over the years I've tried a bunch of different builds and starts, even going into save editing to try more challenging starts.
The big "It" factor is that the world feels lived in and the characters make you care about them besides whether or not you can fuck them or add them to your party (though thats a definate plus). Their are many times where I thought about isekai situations with the game just to get to know the characters better or just have some autonomy outside of the plot.
A good work of fiction is one that makes you want to engage more with the story. That being said, to find that in what is effectivly DnD but your trying(or not ) to keep the demoness from from fucking you and the rest of the world AND that not even the biggest threat to the world, that feel like worldbuilding at its finest.
