Civilization is at its worst when you’re winning. Success breeds complacency as you click the end turn button and acknowledge the news of great accomplishments with the practiced apathy of a regent signing papers on behalf of an infant king. There is an inevitability about your empire’s march through history and it’s easy to feel like a passive pawn.
Rise and Fall, the first major expansion for Civ VI, attempts to address this by introducing global crises, dark ages and citizen loyalty. It gets about half of the job spot on; the fall is much better than the rise.
