[Endoperez]

Order is always good. Luck is sometimes very good, but sometimes just decent. Order provides steady income, especially in the beginning; luck can provide gems, perhaps even items you couldn't have gotten that early without it, or even a fort or a mage you couldn't have otherwise (e.g. a necromancer). Luck could only give you little gold, wrong gems and flagellants, and a couple of bad events as well, if you get unlucky.

It's mostly up to whichever you prefer, and on your nation. Tien Chi generally can use gems of ALL types, and most of their good mages are sacred in all eras, so they can survive with less money and really benefit from the gems alone.
