Crusader Kings III: All Under Heaven
Paradox's biggest CK3 expansion yet drops three entirely new government systems and a 40% larger map - but Mixed Steam reviews signal the depth doesn't land evenly across all of them.
GamerScout Verdict
Best for CK3 players hungry for an East Asian pivot who can accept uneven government depth and real performance costs.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.
Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.
We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.

About Crusader Kings III: All Under Heaven
I've tracked every major Crusader Kings III expansion on a running spreadsheet, and All Under Heaven is the first one that genuinely made me reconsider what this game can be. The map grows by roughly 40%, stretching from Iceland all the way to Indonesia, and that alone reshuffles every mental model you had about where the interesting action happens. The free 1.18 "Crane" patch that ships alongside it extends that geography to everyone, so even players who skip the paid content get a dramatically different world to scheme across. The three new government archetypes are where the expansion lives or dies, and the results are genuinely uneven. The Celestial Government of China is the centrepiece: you climb through the Imperial Examinations earning Merit, manage the Imperial Treasury to fund Great Projects, and track the Dynastic Cycle - a living stability system that oscillates between order and chaos and asks you to time your power grabs correctly. At its best, it feels like a completely different game sitting inside CK3's skeleton. The Japanese Ritsuryo system rewards patient house-building and samurai-coded martial prestige, while the Southeast Asian Mandala structure (best experienced in Angkor, which the developers themselves flag as a friendly starting region) leans on temple development and legitimacy in a way that doubles as a surprisingly good tutorial for franchise newcomers. The Hegemony title, sitting above all Chinese empires as a supreme tier of power, gives long-run campaigns a concrete ceiling to crack through. On paper, this is the most mechanically ambitious DLC Paradox has shipped in years. The friction shows up in the late-game loops. Veteran players have correctly noted that several of the new government forms trend toward consolidating personal power rather than building the dynastic web of obligations and betrayals that makes CK3 tick. The administrative style, where vassals are effectively converted into tax-paying governors rather than political actors, removes a lot of the interpersonal drama that veteran players come for. Spend fifty hours in China and you may find yourself clicking through recurring events with diminishing returns, the novelty of the Mandate system wearing thin once you have stabilized the Dynastic Cycle. Performance is also a known concern: a 40% map expansion means the simulation is running more characters, more provinces, and more events simultaneously, and mid-to-late-game sessions on average hardware will show it. Who should actually play this right now? If you have fewer than 200 hours in CK3 and want the single most content-rich entry point into East Asian medieval history in any strategy game, the answer is yes, with caveats. Angkor genuinely works as an on-ramp. If you are a grizzled veteran who wants the political knife-fighting of Tours and Tournaments transferred to the Tang Dynasty, temper expectations: the new systems are impressive in scope but lighter on the lateral decision-making that makes Europe runs feel perpetually fresh. The mod ecosystem, already active at launch, will almost certainly patch the gaps over time, and Paradox has a post-launch content roadmap in motion. The bones are strong enough that patience will be rewarded.
