Sometimes I daydream about how I would change the mechanics in Crusader Kings 3. I have a lot of ideas on espionage and diplomacy. In my vision of this mod, you no longer know everything there is to know about everybody in the world. I envision this mod being WAY deeper and complex, but as a programmer I realize that something like this would likely be very computationally expensive and likely large for a mod. In my envisioned version of this mod, information is on a per-ruler or per-person basis. Also, information doesn't always stay up-to-date for everyone.
- You will always know all of the information on yourself and your immediate family members.
- If you or your spymaster has an intrigue skill of "excellent", you will know all of the information on your courtiers and councilors as well. The amount of information you know on others in your vicinity scales down with the intrigue skill of you and your spymaster.

- The amount of data you can see on your neighboring rulers scales with your spymasters skill, your diplomatic relations to the target, and the targets' level of fame (prestige). Again, the better your spymaster is at intrigue, the more you will automatically know about your vassals immediate neighbors.
- If a character has a very high level of fame (such as "The Living Legend"), then every ruler in the world will know of your feats and the basic information about you, possibly including your secrets or false rumors spread by your enemies. Being a living legend will not, however, let other people know things such as your exact army size, or how many vassals you have, etc. Only basic information such as your name, age, storied memories, skill levels and prowess will be known to all, even beyond your diplomatic range. The amount of information others know about you (or that you know about others) pre-investigation also scales with level-of-fame.

- Like in Stellaris (another game by PI), you easily can gather information on a foreign ruler and keep it up to date by offering to set up *embassies.* These embassies are ran by you and your chancellor (head diplomat) and the target ruler and their chancellor. As long as the chancellors of both nations and their rulers have diplomacy skill of "average" and up, things will play out normally and information will be shared and updated between the two rulers domains. Opinions between rulers can change mildly as discussions and deals develop within the embassy. If both rulers' chancellors have diplomacy skills of "good" and up, personal opinions of the rulers may even improve slightly (up to a maximum of +5). If one of the rulers in the embassy has relatively poor diplomacy skill, however, relations between the rulers can sour: If the target ruler's chancellor has poor diplomacy skill, they will harm relations between the rulers of the embassy (inadvertently or otherwise), however if your chancellor has diplomacy skill of "good" or above, they can counter-act the harmful effects of the target rulers' bad chancellor, but only to an extent based on the difference of diplomacy skills between the chancellors. If the target rulers' chancellor has terrible diplomacy skill, however then not even an excellent chancellor can redeem relations between the rulers and their nations. If relations get too bad, rulers can choose to send false information on certain things at certain times, renegotiate terms, or break off relations entirely.
- If a ruler breaks an alliance with you or cuts-off official communications entirely, you will keep all of the information you knew about them up to that point, but your information will no longer be automatically updated, meaning it can become out of date. If you are engaged in war with the ruler, your Commander can give an educated guess (based on their military skill) of the targets' military size in the form of a max-min range, changing based on the size of the enemy armies you encounter and the results of the battles. Your Steward can also give educated guesses (based on their stewardship skill) as to the target's financial state (how much money they have and the monthly change), based on old and new information from your other council members.

- If the target-character for your data collection has a low opinion of you, they can choose to send false information to you on things such as their military size, the names and locations of their family and court members, etc. Whether or not your spymaster catches this lie in the act depends on your spymaster's skill vs your targets' spymasters' skill.

- Feasts are now opportunities for gathering information on vassals and rulers. At feasts, you can overhear conversations on people of note (high prestige/level of fame) from nearby or faraway lands, gathering basic information about them. You can ask people for information in-person, but the success of this depends on your diplomacy skill, and even then the information other people know might not always be accurate or up-to-date. Your spymaster can verify the validity of rumors you overhear once the feast is over.

- Your spymaster and chancellor (head diplomat) collects information on selected targets, but that information will not always be accurate or up-to-date anymore. The accuracy of collected data depends on:
- The target's willingness to share such data with you and keep you up-to-date (based on current diplomatic relations (if applicable) and/or the targets' personal opinion of you).
- Your spymasters intrigue skill vs the target's spymaster's intrigue skill (if the target wishes to keep their secrets from you).

- The "Collect Secrets" action no longer just plops the spymaster onto a place and lets them gather information: Now they need to find a way into the target's environment. Most outsiders are kept out of your court by your castle guards, but people of note can request entry into your court, and unless the ruler is paranoid and wants to personally bar or permit access to everyone who wants entry into the castle, requesters will be accepted based on personal prestige, dynasty-prestige, opinions, and cultural acceptance between the requester's culture and that of the liege. If the spymaster gets accepted into the castle, they can begin a plot to collect information on the liege, with agent acceptance within the court being based on modifiers similar to those in murder plots: things such as personal opinion, personality, opinions, and bribes are taken into consideration in the pursuit of sharing and collecting information discretely.
