What exactly are the advantages of each difficulty?

[omniclast]

I noticed playing on Immortal difficulty that AI units had a +3 combat strength modifier that was labeled as coming from "difficulty."

I'm not sure if this was present all game, I only noticed it in the information era in my latest playthrough. Merits further testing.

AI gets +1 bonus for each difficulty level above Prince:

King = +1
Emperor = +2
Immortal = +3 (as you observed)
Deity = +4

Was that the same as civ5, or a new addition? If it was in 5 I never noticed...

There should also be within the XML file fields dealing with growth and production.
Hopefully there's nothing giving free extra charges to AI builders on anything below Deity.

Wasn't in Civ5.
I'm actually glad something like this is in the game.
Just having AI have production bonuses would give them carpet of week units units, and with 1UPT, the troop quality is more important for war performance, then number of units.

Extra setter at Emperor is big red flag for the AI performance, IMHO.

If devs though that 6/8 difficulty requires extra settler for AI to be competitive, compared to olders games where this started at 8/8 difficulty, then AI must be performing much worse then in previous games.

Wow, extra settler at Emperor already? Are there devs working on AI at Firaxis?

Also why are the difficulty bonuses kept secret? You can't find the details in the manual.

We don't know exactly because it's not clearly referenced as in civ5. What I know is that Emperor+ has a free settler. And the AI get some bonuses to yields.

I have found evidence of AI starting units here :
<Row Era="ERA_ANCIENT" Unit="UNIT_SETTLER"/>
<Row Era="ERA_ANCIENT" Unit="UNIT_WARRIOR" NotStartTile="true"/>
<Row Era="ERA_ANCIENT" Unit="UNIT_SETTLER" AiOnly="true" MinDifficulty="DIFFICULTY_EMPEROR" DifficultyDelta="0.5"/>
<Row Era="ERA_ANCIENT" Unit="UNIT_WARRIOR" AiOnly="true" MinDifficulty="DIFFICULTY_KING" DifficultyDelta="1" NotStartTile="true"/>
<Row Era="ERA_ANCIENT" Unit="UNIT_BUILDER" AiOnly="true" MinDifficulty="DIFFICULTY_KING" DifficultyDelta="0.5" OnDistrictCreated="true"/>
This means king+ start with warrior + worker and emperor+ with settler but I'm not sure what the difficultydelta means or ondistrictcreated.

There are also some reference to that kind of stuff
<Row>
<ModifierId>HIGH_DIFFICULTY_SCIENCE_SCALING</ModifierId>
<Name>Amount</Name>
<Type>LinearScaleFromDefaultHandicap</Type>
<Value>0</Value>
<Extra>8</Extra>
</Row>
which I don't know what exactly 8 what it reffers to

What file is that in? I'm having difficulty locating it.

Thanks! Commenting out the extra settler line worked in game so now the AI gets all the other bonuses, just not that extra settler, which is what I was looking for.
