Two luxuries for the amount of space I had available to settle were stingy by the map gods, to say the least. But the number of cows was satisfying. In addition to the 20K culture settlement, Caprica City, having a cow and wheat, I was able to establish five pumps based on cows and started cranking out a settler per turn. I aimed for infinite city sprawl outside of my core and was eventually able to reach nearly 100 cities across my empire.
I skipped Republic and Monarchy. Extended Despotism hurts productivity a bit, but I didn't see any sense in two periods of anarchy stalling wonder production. I waited for feudalism. It does wonders for the unit cap when you need a lot of workers and the military. The ability to pop-rush temples on borders to prevent flips also helps, and sacrificing citizens is easy when you're agricultural and have the Pyramids.
Even with relying on GLib for free techs, my own research paid off. After building the Colussus, I was able to rush the Pyramids. I used the other to rush either MoM or GLib and built the other one. Honestly, I don't remember which I did. GLib requires more shields, but there's less risk of losing it to AI than the other. In either case, I marched into the Middle Ages with four wonders under my belt, which I deemed a good start.
A palace relocation to Wheaties helped shift my core a bit off the coast and opened up the possibility of palace prebuilds for the rest of the game.
I relied on GLib alone for technologies until Printing Press was available. I started research on that immediately instead of waiting for Education to make GLib obsolete. With the AI often chasing other technologies before they pursue Democracy, it seems like you can usually trade PP for anywhere from two to five techs, depending on where everyone is at.
