The greatness of Witcher 3 came mostly from the production values and world building (even in a literal sense, their crafting of the world map) giving a strong sense of place and atmosphere.
Then some pretty decent/fun writing when it came to the dialog and side quests (the main quests was sort of bland, tbh).
It wasn't a great RPG or action game as far as depth of systems, balance, combat etc. and the same was true for Witcher 2.
I'm not sure how CDPR rose to GOD developer status with, essentially, one game, but i think the expectations did go off the charts a bit.
I think CP2077 will play it off in the same areas, with a better emphasis on role play, but i don't expect that aspect to tread any new ground at all.
That said, at that level of fidelity, they do play in their own league, when it comes to RPGs.
