Can anyone give me any tips.
Quickly expand to at least 5 cities. Don't be afraid to drop your science slider down to 20-30%.
Stagnate the cities at size 1 by building Workers until you build some cottages/fur camps. Then build farms, grow to size 2, build more Workers. Connect the cities with roads after building 2-3 improvements around. Rinse, repeat until you can raise your slider to 60-70%. Then build/capture more cities, grab Marble, Stone, and any happy resources (e.g. Gems.)
Research Hunting -> Pottery -> AH -> Mining -> Writing -> Alphabet. Then trade for Bronze Working, Masonry, Fishing, Sailing, Mysticism etc. Then research Math.
Build Granaries everywhere and some Libraries in high food cities as soon as you can, and assign Scientists right away.
Start the Pyramids in one of your cities connected to Stone. Chop down some forests around to get it fast. Switch to Representation as soon as it's complete.
Now research Literature and chop out the GLib in your capital.
Next stop is CS Slingshot. Tech (or trade) to Priesthood, Start the Oracle in one of the secondary cities where you won't run many specialists, and time up its completion with researching CoL + Monotheism. Adopt Confu, then switch to Bureaucracy + Org Rel.
Next thing is Education. Research Paper, then go Metal Casting, Currency, Philosophy, maybe Calendar. Use your first GS to bulb Education (after Paper.) Start Universities in your 5 largest/most productive cities including the capital right away. Chop/whip them ASAP, then set the capital to build Oxford. Chop-chop-chop-whip. Should be done by 600-800BC.
After Oxford whip whatever you can (Forges, Courthouses, etc), and switch to Caste + Pacifism, run max Scientists everywhere.
Then decide whether you go for cottages or specialists. If you go for cottages (easier and safer), beeline to Democracy, switch to Emancipation, and work max cottages. If you go for Specialists, beeline to Chemistry, then Biology. You can bulb Chemistry, Scientific Method and Biology itself.
Now Banking (Mercantilism), Steel (Ironworks), Astronomy, Rocketry, Computers, Industrialism, Satellites, Fusion, Robotics, Genetics, Ecology.
10-12 cities. Don't build anything you don't really need. E.g. Banks or Marketplaces. Better assign a couple of production cities in the plains for building wealth, raise your science slider to 100%, and you won't need any banks. Build a bunch of Workers instead, like 6 per city. Group them into stacks of 3 or 6.
With a bunch of workers you can easily manipulate your production. E.g. if one of your production cities grows slow and far behind the happiness/health cap, farm everything around and set it to max growth. After it reaches the cap (or max workable tiles), replace some farms with Workshops to stagnate the growth and max production.
