Crusader Kings III has 56 different achievements, all using the Steam achievements mechanics. Achievements have no in-game effects; the achievement just pops up in-game, and is then added to the player's Steam profile.
The difficulty of each achievement varies; some achievements are very easy (e.g. Marrying another character), while some are more difficult (e.g. Reconquering all historical Roman territories). The below list groups the various achievements by a difficulty level as assessed by the wiki editors.
Achievements can only be gained in single-player Ironman games. They can be earned while playing older versions of the game as long as said achievements were present in that version. Playing game in offline mode (saving game in offline even once) permanently disables achievements for this savegame. Certain game rules will also disable achievements for the savegame; usually, such rules make the game easier.
It is not possible to gain achievements if the checksum has been changed - either by tampering with game files, or by running the game using mods that affect gameplay mechanics (graphical mods do not affect checksum), or a corrupted installation (the Ironman mode icon will change to reflect this).
List of achievements
- The "Notes" column lists helpful short tips/strategies.
- The Starting conditions column may denote the requirements needed for the player character before the achievement requirements are fulfilled.
- The
column denotes achievements which can't be completed without the use of DLC mechanics (currently 0 out of 56). - The "Ver" column indicates in which version a certain achievement was added. Achievements cannot be earned prior to the version they were added in.
- The "DI" column is for difficulty as assessed by wiki editors. VE = Very Easy, E = Easy, M = Medium, H = Hard, VH = Very Hard, I = Insane, UC = Uncategorized.
