How long do you think it would take to convert the entire world map of Crusader Kings III to a single culture? Not as long as you'd expect, it turns out, as a known CK3 speedrunner has managed the so-called 'one culture' feat in a fraction of the strategy game's game time.
Most large-scale projects in grand strategy games are meant to take up most of the timespan available to achieve. In Crusader Kings III's case, assuming you start in the 867 start date, that could mean you've got a cool 586 years to play around with. Reddit user Doctorsandwich8 felt they didn't need that long, and managed to convert every province that exists in the game to the 'Outremer' culture in just 44 in-game years. 44.
This is a feat that took over 100 hours of planning, and you can read a full write-up of their methodology over on the r/crusaderkings subreddit. This is the fourth such speedrun they've done, following on from their 'one ruler world conquest' (which took 23 years), 'one religion' (which took 29 years), and finally a game where they managed to get the Mongol Empire to use Primogeniture succession rules, which quite frankly is just nonsense. Wonderful nonsense.
