Official rulings
Four official rulings apply to Aeon Engine, newest first.
- This effect reverses the turn order for players established at the beginning of the game. While the order is reversed, anything that cares about this order (such as determining in what order choices are made) will use the new order.
- If the turn order is reversed during a two-player game, or during a multiplayer game that only has two players left, it has no noticeable effect on the game.
- If the turn order is reversed during an extra turn, the next non-extra turn will be taken by the next player in turn order from the last player who took a non-extra turn. The order of any pending extra turns isn’t affected.
- If the game’s turn order is reversed again, it will return to the default order used at the beginning of the game.
