From about the Industrial Age onwards, the number of World Wonders available really begins to dry up. I know that players will be gearing up to go for a specific Victory, but I do think the reduction in available Wonders makes the game slightly less colourful during these eras. With that in mind, here some ideas for new Wonders: Palace of Versailles - Provides +1 Delegate to the World Congress for each Declaration of Friendship made with another Civilisation. Fort Knox - City Produces +5% Gold for each Military Unit Garrisoned or in an adjacent tile (for a maximum of +35%) Large Hadron Collider - Increases total Science output by 50% for 30 turns. Must be built next to a Mountain. Other buildings that might be worth inserting as Wonders include the Burj Khalifa, St Peter's Basilica, and the Empire State Building.
