Sid Meier's Civilization V

Lord, I played at least 200 hours of this game that Steam's aware of. And I still can't remember how to delineate between this and 4 and this and 6.

I believe this is the one that introduced religion. Which while funny I believe quickly became a huge tedious thing where religious units would just completely cover the map and be this stupid slog.

Other than that I have no idea what to call out. Maybe it's worth a replay to recall what made me love it to begin with.
