It seems like you have 2 choices:
1) sawmills to masonry
2) brickyard to writing
Then there's a question of whether you do sailing earlier or later, a little variability for pantheon choice, but either way you want to end up with:
1) 2 cities with a library and monument each, each with a food support town
2) Beeline currency to start placing specialists.
If you don't follow this formula, while you can still complete a legacy path in Antiquity, you'll be behind the entire time especially spamming subpar units to survive wars, and you'll fall far behind during exploration.
If you complete it, you can start to flex a little. Maybe build a lucrative mining town. Maybe go wonders. Maybe try for Great Library. Maybe go to war. But you have to get the default solid start. While you usually can get it, there are many spawns where you can get stuck on a narrow neck of land with only tundra settlements and get crowded out by AI. The AI will automatically hate you if you settle near them (worse when that's the only place to settle), and they will sabotage their own antiquity age to fight out the war. If this happens with the wrong timing, you won't have the means to overcome the Deity buffs the AI gets.
This just all feels awful to me, and it's completely the result of streamlining. This isn't fun.
I am going to try to get into modding to implement my "explosive town growth" idea so the turn 1-70 explore and settle phase is extremely forgiving, even on Deity. As long as you aren't dumb, you should be able to get to a point where any of your first three settlements can flex to be your main production city around turn 50, and from there recover to win the age. In my head, the balancing occurs in the town to city conversion, with normally tight growth rates for cities, and higher cost to convert to city. However, I think towns should grow very quickly so that there's really no way for anyone to fall behind in the tier 1-1.5 level.
I want to feel out the map and my strategy and then commit to a track around turn 70. I don't want to spend turns 1-50 with the same formula every time.
