If Age III ends during the starting player's turn, that is the last round and the game ends immediately. If Age III ends during any other player's turn, there is one more complete round after that, ensuring all players get equal turns.

When a new age begins, cards from ages older than the one that just ended become antiquated (but not cards from the age that just ended). Players must discard all antiquated cards from their hands, and all antiquated leaders are removed from play. Antiquated unfinished wonders are also removed.

The number depends on remaining players in the game: discard the first 3 spaces in a 2-player game, first 2 spaces in a 3-player game, and only the leftmost space in a 4-player game. If someone has resigned, count only remaining players, not the initial number.

No, players have no military actions available on their first turn. All red tokens remain beside player boards initially, while civil actions (white tokens) are placed on the Despotism card based on turn order.

The starting player begins with 1 civil action (1 white token on Despotism). In clockwise order, each subsequent player gets one more civil action than the previous player, so they start with 2, 3, or 4 white tokens respectively.

For 3-player games, remove cards marked 'Republic 4' from civil decks I, II, and III. For 2-player games, remove cards marked 'Monarchy 3+' and 'Republic 4' from these decks, plus all pact cards from military decks I, II, and III.

Age A ends when the card row is replenished for the first time, which occurs on the starting player's second turn. After dealing remaining Age A cards, remove the rest of the Age A deck from the game and replace it with shuffled Age I decks.

All Age III events in both the current and next events decks are evaluated in any order. Any end-of-game bonuses (like the Bill Gates card) are scored. The player with the most culture points wins, with tied players sharing victory.
