A Byzantine-focused expansion for CK2 that adds faction mechanics, retinues, and Orthodox Church depth, but feels thin if you're not already invested in the base game.

Legacy of Rome is the second expansion for Crusader Kings II, and it does exactly what a good Paradox DLC should do: it picks one corner of the map, studies it obsessively, and adds layers that change how you think about the whole game. The headline feature is a reworked faction system for the Byzantine Empire. Vassals now organise into factions with explicit demands, and if you ignore them long enough they will revolt in coordinated blocs rather than one grumbling duke at a time. That single change makes Byzantine court management feel genuinely different from a standard Western European campaign. You are no longer just watching opinion numbers drift. You are watching coalitions form and calculating how long you can afford to insult the Theme of Anatolia before it becomes a military crisis. The retinue system is the other major addition and it applies map-wide, not just to Byzantium. Retinues are standing armies you build and maintain outside the levy system. Early game they are a luxury. Late game they become the backbone of any serious military strategy, especially for players who want consistent offensive power without relying on unreliable vassal levies. Building a retinue composition is a genuine decision tree: heavy infantry and skirmisher mixes behave differently than cavalry-heavy stacks, and the maintenance cost means you are always trading military readiness against treasury health. If you are the kind of player who thinks about build orders, retinues will feel immediately satisfying. The Orthodox Church content is less dramatic but adds texture if you are roleplaying through Byzantine succession. The Ecumenical Patriarch gains more mechanical weight and the autocephaly decisions give Orthodox rulers a different relationship with religious authority compared to Catholic rulers managing the Pope. It is not a full religious overhaul, and players hoping for parity with the Catholic mechanics added by other DLC will be disappointed. This expansion is, in scope, a focused DLC rather than a system-wide renovation. Where Legacy of Rome stumbles is value relative to the full CK2 DLC library. The Byzantine focus is compelling, but the empire is one of the harder starting positions in the game for newcomers. There is a real risk that a player buys this to "try the Byzantine Empire" without the base game knowledge to survive the first fifty years of pressure from Seljuks, Cumans, and internal faction revolts simultaneously. The Mixed Steam rating at 67% likely reflects buyers who either bounced off that difficulty wall or picked up the DLC expecting more breadth. If you already play CK2 regularly and want a sharper Byzantine experience plus permanent retinue access, the calculus is straightforward. If you are still learning the base game, you should probably complete a Western European campaign first before loading this. The mod ecosystem around CK2 is mature enough that many of these mechanics have been touched, extended, or replaced by major mods like CK2 Plus or the various total conversion projects. Legacy of Rome content is usually well-supported in those frameworks. AI quality with faction revolts is serviceable but not spectacular. Computer-controlled factions will sometimes fire revolts at structurally bad moments for themselves, which takes some tension out of the late-game pressure the system is designed to create. Still, for a 2012 expansion that essentially invented a mechanic type Paradox would refine across three subsequent grand-strategy titles, the foundation holds up. Diego, Scout Team

GamerScout Verdict

Worth it for established CK2 players who want Byzantine depth and map-wide retinues; newcomers should finish a base campaign first.

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.
