Bumping this...
Anyone got an opinion on: Tradition opener -> full Liberty -> right side Honor (replaced by left side Exploration if islands)
Opening Trad first leaves a lot of Purples on the table mid-game while helping you little early, and Honor is still unnecessary/inferior by design.
If we're talking earliest win turn, then Left Side Liberty > it doesn't matter. Capital BO Scout > Monument > Archer/UU till 4-5 Pop > Settler > Settler > Settler until there are no more unclaimed luxuries near you. Second city BO Monument > Archer, all other cities Archer first. Buy Order: Worker > save for CB upgrades, sometimes buy a Caravan if you're close to multiple civs. Get 6-8 Archers by Turn 50'ish, then upgrade to CB's. Sell luxuries aggressively.
Whatever you do after Left Side Liberty, your only needs are Happiness and Science for the rest of the game. That probably has you finishing Liberty for the Worker to improve Luxuries, then Meritocracy for Happy. The closer is a Scientist for either an Academy or Bulbing Machinery if you're close enough to win with it. Also, Representation does help a lot w/ later era policies, which are clearly better than early era ones.
The best mid era policy for Domination imo is Mercantilism in Commerce. Not so much for buying units, although that helps, but the extra Beaker from Gold buildings is nice because you want as much Science that's not related to Population as you can get. You'll have Markets/Banks quite early anyway. If you have enough Gold though, Patronage to Scholasticism can be better. I'd say 4 CS allies is about the tipping point where I go Patronage instead. Also in certain circumstances where a conquered neighbor's religion claimed Pagodas, going the first 3-4 in Piety can be worth it.
On Ideologies, I've come around recently to the idea that Autocracy is a great track. Level 1 should be Fortified Borders > Industrial Espionage > United Front/Mobilization. Level 2: Militarism > Police State. Third Alternative is very strong though if you still have trading partners left. Total War and Nationalism are also better than any policy outside your Ideology too, and if you plan on getting 3 level 2's, you get either of those first before Police State. That's why you load up here instead of early eras. Level 3 is Gunboat Diplomacy every single time. A lot of the time your army will be gaining CS Influence from the other end of the Continent. The common theme here is that bonuses to attacking are bad. Same goes for Honor as it does here. If you use your units well, combat strength is not something worth wasting any Purples on. But the important thing is the Happy. Just put all cities on the Walls/Barracks lines of buildings, even though you don't need those buildings themselves. The Barracks line doubles as the Colosseum/Zoo line of buildings. If you're doing fine on Happy, keep building those buildings anyway and just sell your luxuries to that last AI on good terms.
