I'm not good player compared to vmxa or other but these are my tips, that they gave me or I learned:
At the beg of game, build 3 warriors, use 2 for exploring unknown (dark areas). Build settlers, skip the part of building temples, they are not worth before town is size 5-6. Building settlers/workers lowers city pop, so those won't start revolting.
Do not build wonders, in capital, unless near end game, as Wonders only weaken you.
Wide spacing of cities is not worth it, try to place your cities in more compact way:
CxxC wherein C is city and x is tile. Advantage with this placement is that you can get more soldiers to defend and wide spacing will not get useful before industrial/modern age. Towns can grow to around size 12 without hospital, that is maximum and hospitals are faar away.
Not every town needs library and marketplace.
You got HUGE amount of regular units, whenever possible build barracks first then veteran units from there, that one HP counts ALOT.
Helipolis(size 9) with barracks is producing wealth, switch it to military unit.
You got 9 workers for 9 towns, you need 18 workers for 9 towns.
Try to improve the tiles that are worked upon with atleast a road, if no time to mine/irrigate. Road gives commerce, commerce gives money AND science.
In byblos, you got joker, Switching it into specialist (either scientist or taxman) does not hurt the town, it will still be content. Why to turn away of 2 gold or 3 science points?
Why is your capital building courthouse? No use, let it produce either workers or units.
I can see pyramids ´, I can see temple of artemis, I can see Statue of Zeus. Instead go and read the 4 rules of wonder addiction, in war academy (link at bottom of post too)
It is better mine the grasslands and irrigate the plains. (unless town is in half mountainy area.)
You have not explored, 2 warriors should be exploring to make trading contacts.
Your reasearch problems come from not having enough roads. Thefor less commerce and gc. You should have road on tile that is worked in city.
Al, almenia is not connected with roads, connect it. It also has a settler fortified into it. Wake it up and do something with it! You got plenty of area to expand to.
Id reccomend for you to change government into republic, once you can. Pi ramsess is producing a marketplace but it gives only 2 gold per turn, use it to produce workers, and road area around pi ramsses (that is being worked), that will give higher science and gold income.
Just notes for more advanced players to ramble about...
