Ultimate Guide to get the achievement "You're the Demonstrably Greatest"

You're the Demonstrably Greatest
Achieve the highest possible rank in Conquests of Alexander at Deity difficulty.

This means that you must complete this scenario in 37 turns maximum (by selecting Divinity difficulty) as well as being first in the score table.
The highest rank possible in this scenario is "Alexander the Demonstrably Great" with 200 points.

Knowing that a city represents 5 points and that there are:

• A Macedonian city Pella (5 points);
  
• A settler at the start (5 points);
  
• 28 cities to capture (140 points).

So to obtain the remaining 55 points necessary to exceed 200 points, you must found 11 cities. Indeed, we must not equalize the score but exceed it.
In addition, you must found cities before capturing all those of the Persian Empire because the scenario ends once the latter is no more. This scenario will require patience and reflection. It is no longer a question of development, but of combat. Indeed, no tree of technologies or dogmas; no doctrines, diplomacy or religion. You must therefore form an army worthy of the name and control all these lands.

The scenario, however, adds a constraint:
You only gain Great General points by killing enemy units with Hypaspists and Hetairois. This action earns 5 great general points per elimination.

The leader of Macedonia Alexander offers significant bonuses:

• MP +1 for settlers.
  
• All towns are founded with 2 citizens and a granary.
  
• Districts are built more quickly and camps contain a Basilikoi Paides.
  
• Cities do not generate war wear.
  
• All military units are fully healed if the player captures a city with a world wonder.

There are 5 cities that have a wonder. As a reminder, capturing a city with a wonder completely heals all your units. So don't forget to play all your units before capturing the city. Here is the map which presents the position of the 5 cities having a wonder:
Here in order of capture the 5 cities with wonder:

There are many improvements on the map, 155 to be precise. We must therefore not deprive ourselves and thus encourage looting. So in certain cases, it can be interesting to loot an improvement before capturing a city. Knowing that the captured cities will have very few inhabitants, these improvements will very rarely be exploited. The positioning of the 155 improvements:

You should also know that in this scenario, looting does not have the same rewards as in a standard game. Most of them bring healing. Here is the list of improvementswith rewards:

For information, we differentiate a quarry from a mine because the first is only built on the resources of Gypsum, Marble and Stone.

In this scenario, we will instead focus on training close combat units, light cavalry and siege units. We will also see ourselves in possession of anti-cavalry units.
Let's compare them.
The Hypaspist is the most powerful unit in the scenario. To compare with the Swordsman, the Hypaspist has +3 attack strength. Additionally, it is excellent for capturing cities. Use it instead to besiege cities, but don't hesitate to eliminate opposing units to accumulate Great Generals points.
As for the Immortals, send them to the front line: they have great defense.
The Hetairoi is the second most powerful unit in the scenario. Its advantage is that it moves quickly thanks to its 4 movement points. Combined with the advantages of the Great General, this unit can make great trips. Use it to eliminate units to increase your Great General points, and support your Hypaspists to capture cities.
The catapult only requires 2 movement points to fire. Thus, with the Great General bonuses, the latter can move before shooting.
In reality, these units are not very powerful. Spearman training is not justified. We will still obtain 2 Hoplites to strengthen our army at the start of the game, but do not count on them to manage the most important battles. However, they will be a little extra for the assault in the South-West where there are many cavalry units. 7 so-called special units are available in this scenario. A special unit is a unit offered by certain cities if they are captured with Alexander the Great nearby (i.e. one tile from the city center). Here is the position of these cities on the map:
5 of them also have a wonder. Here is the list of cities and potentially recoverable units:

This will impose a path for our Great General Alexander the Great, I recommend recovering the Hoplites in Athens, the Galley in Halicarnassus and the Immortals in Parsa. Optionally, you can collect the Varu from Potala, but it will not be very useful because it will be at the end of the game.

Great Generals are of paramount importance in this scenario. However, despite their great added value, they remain very fragile:

• If Alexander's great general is killed, you lose.
  
• If another great general is eliminated, he disappears from the game.

So do not leave your great generals defenseless. Make sure they are out of reach of enemies, or that they are protected by one of your units (by having them share the same tile). The big advantage of great generals is that they give combat strength bonuses as well as movement points to your units.
Please note, the operation of these bonuses is not identical:

• Units gain a movement bonus at the start of the turn (so be precise about the position of your great general before the end of the turn).
  
• While units receive the combat strength bonus during the turn (so make sure your unit is within the diameter of the bonus before attacking). Indeed, I often found myself comparing the damage of my unit close to my great general as it moved out of the diameter to attack. In this case, the attack bonus is no longer.

Also remember that it is possible to transfer a great general from city center to city center with this button. The great general Alexander the Great is under your control from the start of the game. As for the other generals, you will have to unlock them with great general points. A great general requires 50 points to be unlocked. In particular, it can be purchased with gold. This will require 950 gold if no points are accumulated. The price goes down depending on your number of points already collected. Here is a start of the list of great generals present in the game:

Be careful, the order of appearance of the Great Generals is random, there is no precise order!

Firstly, we can see that Alexander the Great's bonuses are disproportionate, he will therefore be present for the conquest of the most defended cities.
Then, we realize that there are great generals who are more combat oriented (+10) and others movement oriented (+2). So be careful to use a “speed” great general when you need to move troops, and to use a “combat” great general when you need to attack.

As you progress, I advise you to form three armies. There will naturally be the army of Alexander the Great which will make the greatest distance; as well as two others who will be responsible for besieging cities that are not on the main path.
Here are the paths I recommend:
Legend

Not many units will be needed for the Southwest zone. I would advise setting out to conquer with:

• 2 Hoplites (these Anti-Cavalry units are not very strong, and most of the cavalry are found in the South-West),
  
• 1 Hypaspist (to help with siege thanks to its siege bonuses),
  
• 1 Catapult (because two cities have walls),
  
• 1 great general (except Alexander the Great).

Don't panic, your first unlocked great general may arrive during the conquest. Don't wait to unlock it to start the assault.
Better choose a General with large strength bonuses to capture the cities, then a General with large speed bonuses to return and capture the last two central cities. This army will be formed during the great division. If possible, consume your gold to unlock this second great general before dividing the army of Alexander the Great. This passage is rather subjective because your income should start to be significant: strengthen your armies by buying units (generally Hetairois).
Favor a General with large strength bonuses. The vast majority of cities in your possession will be described as occupied. This therefore means that it cannot increase in population. And as training units with production takes too long, the strategy to adopt is to concentrate on gold to be able to buy units. In this scenario, gold is the crux of the matter.
As soon as you capture a Persian city (because those of the city-states will not be in an "occupied" state), you must therefore prevent your citizens from working for food. For reasons of speed, I even recommend orienting the concentration of the city as follows:

• Exclude food yields.
  
• Focus on production yields.
  
• Focus on gold returns.

If the units take too long to produce, then what should we build? Each of your cities (apart from your capital and potentially Athens) will have to build a camp and then repeat the Encampment Training. This project allows you to generate gold as well as great general points. That's all we need!
Encampment training yields:

• 15% of its gold production per turn,
  
• 22% of its production in great general points once completed.

Source: Civilization Wiki - Encampment Training[civilization.fandom.com] About the capital, this is the one which is going to form the majority of the settlers.
For Athens, in order:

• Repair the granary,
  
• Repair the camp,
  
• Train a settler,
  
• Repeat the encampment training.

The first action is to capture the Athens encampment with a Hypaspiste. For reasons unknown to me, this action may seem random. Sometimes it works, sometimes it doesn't. Try to do this action as quickly as possible after loading. Once done, I advise you to save the game.
Approach Alexander the Great, then attack Athens first with the archer, then the Hetairoi.

On the other side, attack Sparda with your Hetairoi, attack the camp with your archer (to gain experience) and approach your Hypaspiste.

Found a city with your settler so that you can create a camp (optionally under the first). Don't forget to exchange the tile (in the management of the city's citizens) to be able to build the camp. You can launch the formation of a military unit (Hypaspiste or Hetairoi) in the capital.
You can now take Sparda by attacking with your archer, your Hetairoi and your Hypaspiste. Do it before taking Athens because the latter has a wonder and will therefore heal all your units once captured.

Don't forget to approach Alexander the Great towards downtown Athens to be able to collect the 2 Hoplites. Attack Athens with your archer and capture it with your Hypaspist (the Hetairoi will not be powerful enough to capture it). Then bring your units back to the East.

You can start granary repair in Athens.
I recommend using your two archers, two Hypaspists and especially Alexander the Great (who should be near the city center) to capture Halicarnassus. This may take several turns, but the galley will allow you to defend your coastal cities without having to buy one. You will end up having several builders but very little to build. I still recommend planting in your first founded city. This will increase your gold intake.
Then you can simply use them as bait when facing the enemy. Who knows, sometimes this sacrifice can save your defenseless catapult. Depending on the position of your unit, the healing provided is different:

• +5 HP in enemy territory,
  
• +10 HP on neutral territory,
  
• +15 HP on allied territory,
  
• +20 HP in town center or camp.

To conclude, this scenario will judge our ability to win a major battle in a limited time.

Production becomes secondary because it takes too long to form units: we're mainly going to launch Encampment Training to store as much gold as possible. It is this gold that will allow us to buy units.

The units that we will buy are generally Hetairois, Hypaspists as well as Catapults.

We don't forget to move our Great Generals carefully to give the movement and strength bonuses at the right time. But protect them because in this scenario, the Generals are vulnerable.

Alexander has bonuses: all units heal completely when capturing a city with a wonder; and can recruit units if he is near certain cities when captured.

With all this and a few attempts, you should be able to capture all the cities as well as found 11 additional cities to collect the 205 points needed to obtain the achievement. Good luck!
