Synopsis

A grand strategy game set in medieval Europe and beyond, where you play a dynasty rather than a country. You arrange marriages, plot against rivals, wage wars and try to keep your bloodline in power as each ruler ages, dies and passes the realm to an heir who may not be up to the job.

What people say

Critics praised its character-driven take on strategy, where family drama and scheming produce memorable stories, while noting its steep learning curve and dense menus. Over the years a long run of expansions widened it into one of the deepest games in the genre. Players today still argue it offers more systems than Crusader Kings III, but many find the base game thin without paid expansions and say it overwhelms newcomers. The base game has been free on Steam since 2019.

✓Controls feel natural on a modern controller or mouse and keyboardMouse-driven map and menus suit the genre well, though there is no controller support. Source: pcgamingwiki.com.
✗Menus, text and interface are clear on today's screensThe interface is a crowded web of small windows and icons, and there is no confirmed support for scaling it on 4K screens. Source: pcgamingwiki.com, forums.pcgamer.com.
✓Saving is fair: free saves or frequent checkpoints, little lost progressYou can save at any time outside Ironman mode, with cloud sync, so little progress is lost. Source: pcgamingwiki.com.
✗It teaches itself: no guide needed to make progressNewcomers often feel overwhelmed and turn to outside videos to understand its systems. Source: forums.pcgamer.com.
✓Pacing holds up: little grind, filler or forced backtrackingAdjustable game speed lets you skip quiet years, though large save files slow the late game; evidence on pacing is thin. Source: pcgamingwiki.com.
✓Camera and movement never fight the playerThe map view scrolls and zooms freely and no source reports trouble with it. Source: pcgamingwiki.com.
