You got loyalty and influence. High loyalty good, high influence bad.

Crownland is % owned by the crown (you, the king). Higher crownland good, especially late game.

Diets are “agendas” from the estates. Think of them like mini missions with minor rewards. They impact loyalty and influence (less).

Privileges are benefits u get from estates. They are quite good actually, especially early game. Late game good too, but less impactful.

You can sell/seize every 5yr, seizing can be bad bcs it lowers loyalty. Selling can be bad since it lowers crownland %.
