95% of my desire to play Civ (and there’s a lot of it) is to play super long single player games, ideally modded ones that extend it further, neither Civ V nor Civ VI were able to give a REALLY good experience for that. Civ V was too unstable and Civ VI was also a bit unstable and the AI was somehow even worse at playing in an interesting fashion in that context (ie. Trying to play through a world history with shifting borders and diplomacy)
