Alright, I use to play the old Civilization games back in the early 2000s. I think my favorite one was the fourth game that came out in 2005. We had two disked versions of the game but that was the one I remembered loving. I do have Civilization Beyond Earth but I haven’t fully played it. It’s a bit different from the Civilization games I have played in the past.
Here is a link to the main website: (The game list is at the top left)
Hard to say since I only played the last two. And I’m such a perfectionist when it comes to games that I haven’t gone through the Medieval Era (I kept starting a new game).
