I tend to get native language, definitely on the higher difficulties since it can offset the initial unhappiness that can happen upon founding a city. (So it became habit, and I'm a Spiritual leader, might as well milk that for all its worth)
I tend to beeline Oral Traditions right after that, then see what my immediate needs are.
Usually opt for for the tech that unlocks the 'Stone Tool Maker', that grants money, production and science.
P.S
Unless its radically changed, I usually try not to play spiritual leaders... but I think the very limited anarchy thing is still there.
How can spiritualism benefit the native language tech?
