I feel like a lot of it's imitators such as AC:O, Mass Effect Andromeda, Horizon Zero Dawn (i'm gonna get slaughtered for mentioning that one) copied aspects of Witcher 3 but never really understood why some of those things were so special, e.g the side missions, the very grey morality and the world building. I didn't just like Witcher 3 because it had side missions, I loved it because of what those missions and characters were and the impact they had.
I'm liking this game but there are some things it could improve on. I can't deny it's absolutely gorgeous though and the combat is fun.
