Metal Casting was more to get us to Optics than to build forges right away. I could go along with a path that helps the science rate instead, as long as we don't forget that we have 2 cities to settle and see nowhere better than in place at the moment. How long to wait?
I see Priesthood as still a good path if we then get CoL and make some courthouses. Currency is not as attractive since only domestic trade routes would be added. Exploring is still key. What would we need to tech for the GSci to bulb Optics? Maybe we should tech alphabet, MC, and Compass and then bulb it. But we'll get another GSci before then, so settle or academy would be best for the moment.
The longer we wait to settle our 7 cities, the slower we approach our goals and the farther we fall behind.
I see no value in doing archery/HBR and horse archer rushing SB. We get more from friendly relations than we would from taking his land. The same is probably true for any other AI we can presently reach.
Exploring first; economy only in so far as it speeds the time to astro.
