A leader's Personality is defined by one or more personality traits attributed to that race. These traits decide how the AI plays that race. Some traits also add flavor text when the player is using that race, or when the AI is speaking to the player. There are currently 12 Personality types which are related to specific play styles, such as Wealth or Culture, that you can choose from. When playing as a custom race, you can choose which traits you want your race to have, while vanilla races cannot have their personalities changed unless you mod the files for that race. When making a custom race, it is best to keep the personality traits to around three, or the race will have conflicting interests, and will play generically.
