well again you get the same "apocalyptic"/"end-of-civilization-as-we-know-it" threads whenever a new Civ is released.
Having played Civ5, CivBE and now Civ6 pretty much from day one, I would say they were all quality products from the start. Yes they have some AI or balance issues, or some bugs, but all the features work and they are fun to play and eventually the games were improved/fixed by patches.
When I first saw all the negative comments in Civ5, I was concerned, until I realized most were unfounded or gross exaggerations.
When I then saw all the same negative comments in CivBE, I was annoyed, especially once I realized most were unfounded or gross exaggerations.
When I now see all the same negative comments in Civ6...well at this point, I just laugh.
..as a wise oracle once put it:
