What exactly is the effect of loyalty in the game? Is there any point in improving it? I remember reading at some point that it affected the efficiency of a planet, but other than that...
Traciones don`t work, there effect was removed to protect Guardian`s loyalty. And no they won`t be an artifact to increase loyalty, you Guardians would have massive incomes and your income is fine how it is. It`s supposed to be a hard race to play, and your ships have low upkeep to compensate.
While we`re at it, may I suggest we have some sort of artifact to boost loyalty of an empire? I know it`s for my selfishness, but if we make it as hard as gordo (maybe harder) then nobody should stop the people who are making it.
I`m guessing your a commercial terran, so yeh increasing your loyalty is not something you shouldbe worrying about. Try and get asmuch land as you can, and spend your time when your not fighting researching commercial.
If you are a tax based empire it increases your income by 0.5% per point, so up to a total of 2500%..An absolute neccessity for tax based empires, and just a nice bonus for anyone else.
