The big strategy game news of the fall is undoubtedly the release of Civilization VI on Oct. 21, but it’s not quite the only game in town. In addition to the recent release of XCOM 2 on consoles, the other biggest grand historical strategy game around is getting a major new expansion on Oct. 11. Europa Universalis IV: Rights of Man from Paradox Interactive will dramatically extend the diplomatic game for one of the most in-depth strategy games of the last few years. Let’s take a look at what’s new, based on the latest dev diary.

Europa Universalis IV: Rights Of Man Features And Dev Diary

The expansion focuses on diplomatic and government changes, especially to the Great Powers. Great Powers gain new abilities, some focused on maintaining the balance of power. Rights of Man also expands the royal court, adding queens and princes consort. Rulers gain personality traits and the ability to abdicate; it’s a clear nod to Crusader Kings II.

Various regions around the world also get a boost, with the Coptic and sub-Saharan African religions fleshed out a bit and new government types added for the Prussians and the Ottoman Turks. The use of unique mechanics for different empires and regions keeps Europa Universalis IV feeling fresh, whoever you’re playing.

Rights of Man also acknowledges that a lot of states in the game’s time period were still quite decentralized, and adds gameplay to match—including more power over states under your command. The expansion also comes alongside a major new patch­—a Paradox trademark—that improves the AI and adds a new culture system, as well as a new technology system. Western Europe is no longer automatically the most advanced technologically as the game goes along; the new system is much more dynamic.

Europa Universalis IV is out on Oct. 11 for $20, and is one of the largest expansions to the game thus far. The game has sold over a million copies worldwide, so it’s no slouch! Are you going to give the new expansion a try?
