Golden Century serves as an "immersion pack" for EU4. These immersion packs are smaller DLC packs for the game, typically focusing on one geographical area rather than systems that impact the entire game. Golden Century really helps flesh out the Iberian nations and helps to add more depth to the colonization process in the New World. Another great addition to a great game!

As an entirely new nation to the long-running series, Australia is a very welcome addition to Civ 6. This Civ has not only a unique unit and a new building, but also a new tile improvement - generally major boons for the Civs which have them. Also included in this pack is a new Scenario - Outback Tycoon - which is centered around colonization of the continent. A returning wonder, Uluru, is also contained in this pack. Would definitely recommend!
