That's way oversimplified and actually in most cases not even true.
These aren't oversimplified. Good players will have an idea of how they want to win with a given civilization at game load and will pick their first policy tree based on this. IE: Good players have goals and then try to obtain the means to help them achieve these goals.
I would be an utter and complete moron to pick authority as Venice if I had no intention of expanding through conquest.
It would be silly and masochistic to not pick authority if I intended to piss off neighbors as expansionist America in a high difficulty game.
A scientific Korea that doesn't pick Tradition is weird.
An aggressive Songhai that doesn't pick up authority to farm barbs in a map that supports barbs is bad.
For
nearly every civ in the game, if you have an intended victory type with that civ there are policy trees that you simply either A) need to choose
or B) shouldn't choose. This is irrefutable.
I urge you Funak to generate a list of situations of where a civ has A) an intended victory type
and B) all 3 policy trees are optimal. I guarantee that my list of situations where a civ has A) an intended victory type
and B) there a policies that that civ should or shouldn't choose will be bigger.
Your intended victory type can change throughout the game and your actual victory can be different as well (culture victories seem too easy still). But by the time you pick your first policy you start understanding your limitations.
In simple terms,
Tradition is best suited for: Tall Peaceful Play
Progress: Wide Peaceful Play
Authority: Wide Aggressive Play
While you can surely play a diplomatic game with authority (big stick policy) these are just general guide lines. Progress provides benefits for wide civilizations without giving the aggressive bonuses of authority.
If you want to do a slow conquest to avoid having everyone you meet think you're bringing on a new dark age, Progress is a decent choice.
Oh, look, Wide/Relatively Peaceful.
To OP: I'm not particularly upset, hence my use of words like "please." But if I ask people anywhere for help and guidance I try not to say things like:
I don't want to be an ass but you are staying general when my questions are kind of precise.
Just answer them one by one, it's easy you will see.
Enginseer, at least, tried ^^
Instead, maybe perhaps, "could you be more specific and elaborate? Thanks!" This will prevent you of getting responses like:
I'm sorry I just tried to not be an ass and make it clear how silly your original questions looked, but sure, here I'll go.
I also don't understand how you believe that the comment below can't be taken negatively.
Sorry, if I hurt you, I'm black and being blunt is a cultural thing. I'm never "passive", I've never meant to hurt anybody. I'm looking for advices.
What I want is a real peace of your mind, not just some generalist advices, CBP's tool-tips are good enough
ps : Try to smile, I can feel it when you're writing while edgy.
ps 2 : Fear not, I will "try" to contain myself.
I'm still going to try and help you however!
Because you don't like "generalist" advice (you should look up that word, it doesn't mean what you think it means)...
Anytime you play a civ with free city connections or situations where city connections are widely abundant AND you intend on playing peacefully you get more from Progress than Authority.
This is because A) you milk the Progress policy that gives you free science per city connection more easily and B) the Authority policy that gives 50% reduced road maintenance is of diminished value.
Examples:
Iroquois with lots of Forests, the Progress's production/building bonuses synergies extremely well with their Longhouses.
Carthage with mainly coastal cities, the lack of a gold boost until Progress's finisher is offset well due to Carthage's UA.
Sometimes Songhai should get Progress, but most often authority is better due to barb farm.
