Civ has a lot of old fans since civ 1 or 2 that just buy and play any new civ game that comes out. I had:
Civ 1
Civ 2 + Addons
Call to Power (which was no official civ)
Sid Meier’s Alpha Centauri
Civ 4 + Addons
Freeciv
Civ 5 + Addons
Civ: Beyond Earth
Civ 6 + Addons
Unciv
Hearts of Iron
Europa Universalis
Sid Meyer’s Civilization
Armored Core (with a bonus freebie title)
