Crusader Kings III
Determination: Explicit — Corruption 3
You can play as the literal Catholic Church, including as Pope, with simony and antipopes as core mechanics.
The “By God Alone” expansion lets you play as the real Roman Catholic Church, up to becoming Pope, with simony, corrupt antipopes, and Church scandal as expected, simulated mechanics rather than rare edge cases. Softest fit on this list: a historical simulation, not deliberate satire.
