Funny / Crusader Kings

Trailers and Promotional Material:

In-Game:
  • There can be some rather... odd AI interactions within the game. For example, as an Irish King, it's possible to (through bloodline ties to the throne) become nominated by a Faction to become King of England... and actually attain the throne. Granted, it's likely that your dynasty will be kicked off as soon as there's a Succession Crisis, but for that particular King's lifespan, you'll be wondering how the hell it happened.
  • It's more than possible for a wife and husband to be King and Queen Consort of each other's territory (the King of one country is the King Consort of his Queen's country, and vice versa). They can go to war with each other, whilst being lovers and popping out kids.
  • There is a line of scripts that cause an old ruler to expire after consummating his marriage with an attractive, young, lustful wife. His wife gets the "depressed" trait after his death.
  • In certain cases, counties, duchies and kingdoms with the same name are seperate from each other due to independence revolts and the like. Behold; the three eastern powers of Perm, Perm & Perm.
  • Combining the "Commit Suicide" option and gaining prestige/ducats from marriages with royalty will make for some Black Humor.
  • The Way of Life expansion introduces, among other things, the ability to seduce courtiers. One of the event options after your love-making sessions goes "Vidi, Vici, Veni."
    • It is not only limited to courtiers. Female rulers can seduce other male rulers too. Your husband will get a -200 opinion penalty because you are a harlot and will confront you while throwing furniture around. The female ruler can then tearfully reassure him of her love and proceed to seduce other guys.
  • Commissioning a Runestone with a lunatic character made in Ruler Designer produces an interesting result.
    Kettil, proud son of a holy union between Odin, a wild mare and three forest gnomes, paid Óleifr handsomely to carve these runes. With his flying longship and crew of twelve singing rabbits, Kettil earned his fame by sailing across the Norse lands solving crime. May the Shining Tentacle preserve us all.
  • With the Charlemagne Expansion, Chronicles were added, listing all your accomplishments. In the event you have a year where nothing particularly interesting happens, the game inserts something about one of your provinces; usually this will be something like "An unusually large number of births in [Province]". Sometimes however you get something like "A three headed goat was born in [Province]."
  • Anyone can marry anybody of any age, which makes for some cringeworthy pairings such as a sixty year old ruler having a sixteen year old wife.
  • The Lustful trait is more of an incredibly useful trait to have rather than a disadvantage due to the fertility boost as it guarantees your dynasty's continuation... even if your ruler is sixty years old and his wife is sixteen.
  • The button text for some of the more dastardly actions frequently delves into Black Comedy. After successfully arranging for someone to die by poisoned wine, your character might comment, "I think I will celebrate with... beer."
  • "That Time a Horse Conquered the Ancient World". The short version is, a player exploited a loophole in the rules regarding horses (a character with the "Lunatic" trait can make a horse his chancellor, as with the historical Caesar Caligula) to create an entire dynasty of horses that then restored the Roman Empire.
  • Due to the fact that the game provides little incentive for AI or player rulers to follow history, some bizarre culture/religion/location combinations can occur. Such as Jewish Norse Greece.
  • The Lunatic event where your character seduces a rosebush can actually produce a child.
