  Find the person behind the list

  A useful claim, an exceptional mind or a powerful ally: find promising names in a long marriage list and see what makes them stand out.

  Compare candidates without losing the details

  Hover an MCA score for its component breakdown. Choose MCA: by score to bring the highest-scoring candidates to the top.

  Compare candidates from other courts or your own, using the same core weights. Adapters can add setting-specific opportunities.

  Scores do not change acceptance or modify candidates. MCA points are separate from Parley's treaty score.

  What the score includes

  • []Visible inheritable qualities: intelligence, beauty and physique tiers receive +10, +20 and +30; negative counterparts subtract the same amounts. Other supported active inheritable traits have their own weights. Hidden/recessive genetics are not inspected.[/]

    []Skills: up to 30 points from five public skills and the standard assist-spouse contribution. Effective age below 16 or incapability gives zero. This does not assume eligibility to serve on your council.[/]

    []Age-based reproductive potential: a 0–20 index of effective age and visible restrictions, not birth probability. A child's zero describes current potential, not lifelong childlessness.[/]

    []Dynastic prestige potential: −5 to +45 from the dynasty marriage-prestige table: dynastic standing, not the pair's exact reward.[/]

    []Explicit claims: the strongest contributes up to 24; pressed claims weigh twice as much as unpressed claims of the same rank. Marriage does not immediately transfer claims or titles.[/]

    []Potential alliance: up to 100 from the ally's military strength relative to yours, only when the native row reports it. Assistance is not guaranteed.[/]

    Components and adapter contributions add up to the score. These are comparison weights, not percentages or a shared resource. Inspect the breakdown for what matters to your plans.

    Court position, arranger opinion, reluctance to release courtiers, hidden fertility/health, secret parentage, predicted children, succession queues and the selected couple's full value are outside the model.

    How to use it

    • []Open a marriage picker and set the game's normal filters.[/]

      []Hover an MCA number to inspect its components.[/]

      []Close the filter panel and choose MCA: by score for descending score order. Equal scores keep their current native order; unavailable scores go last.[/]

      []Choose Default list to restore the native ordering and filter controls.[/]

      The pinned-player row stays pinned. Changing picker side, marriage type or candidate context clears the sorted snapshot. Selecting a moved row selects its displayed character.

      MCA scores and sorting apply when arranging as your own ruler. Switching to a puppet clears the sorted snapshot and uses CK3's native list without MCA scores or sorting.

      Compatibility and load order

      Vanilla file replacement: gui/interaction_marriage.gui. MCA supplies its own score interface, sorting and cleanup. It does not replace gui/shared/lists.gui, arrange_marriage_interaction or marry_off_interaction.

      Another gui/interaction_marriage.gui replacement needs a functional patch; load order cannot merge files. A mod changing only gui/shared/lists.gui can work if its row retains vanilla's character_relation block in the name/age column. This is not blanket list-mod compatibility.

      Optional combined load order:
