Personality defines how the AI plays that race. In certain situations, the AI will follow specific strategies based on its personality. Personality also affects diplomatic disposition, as well as voting behavior in the United Planets. Some traits also add flavor text when the player is using that race, or when the AI is speaking to the player.
When playing as a custom race, the player can specify its personality. It is best to keep the personality traits to around three, or the race will have conflicting interests, and will play generically.
