I and II are good, III is…probably the weakest of the early civ games. IV is my personal favourite so I’m a bit biased, but it’s pretty unique, there isn’t another game like it in the series, even if it does have some major problems (like the stack of doom being pretty much mandatory).
I only played Civ V and Civ VI. I believe I have III and IV, and I played a little bit of IV iirc. I should try Civ I-III when I have the time.
