I have (at long last) looked into the tech tree with more detail.
But first, here is a quick broad outline of the
HISTORICAL events....
(Things in the scenario will obviously depend upon how it is played)
Historical Events
----------------
336BC = Darius & Alexander both become Kings, Alexander made Captain-General of the Corinthian League, rebellion lead by Khababasha of Ethiopia in Egypt.
335BC = Alexanders Thracian & Illyrian campaigns, the sacking of Thebes, Darius re-conquers Egypt.
334BC = Battle of Granicus, siege of Miletus, Alexander disbands his fleet, siege Halicarnassus, plot against Alexander foiled.
333BC = Death of Memnon, the Gordian Knot, Alexander becomes ill, the battle of Issus, capture of Darius family, Darius 1st peace offer.
332BC = Siege of Tyre, Darius 2nd peace offer, siege of Gaza, Alexander enters Egypt and becomes Pharaoh. (Ariarathes, satrap of Cappadocia, invades Asia Minor, but is defeated by Antigonus)
331BC = Visit to the Oracle of Ammon at Siwah, foundation of Alexandria-on-the-Nile (the first of many Alexandrias), Darius final peace offer rejected, battle of Gaugamela, capture of Babylon, Antipater suppresses a Spartan uprising at the battle of Megalopolis, battle of the Susian Gates.
---------------------------
330BC = Sacking of Persepolis, Greek allies dismissed, Darius murdered and Bessus becomes Great King, Alexander starts using Persian Mounted Javelinmen, Conspiracy of Philotas and execution of Parmenio. (Alexander begins to adopt Persian dress and customs)
329BC = Thessalians dismissed, the Bactrian campaign, capture and death of Bessus, revolt of Spitamenes the satrap of Sogdiana
---------------------------
328BC = The Sogdiana campaign, Alexander kills Cleitus the Black in a drunken rage, defeat and death of Spitamenes.
327BC = Capture of the Soghdian Rock, Alexander marries Roxane, recruitment of 30,000 Persian Successors, the Pages Conspiracy, start of the Indian campaign.
326BC = Battle of Hydaspes against Porus, death of Alexanders horse Bucephalas (ahhh), the MACEDONIAN MUTINY at the Hyphasis river, campaign against the Brahmin cities of the lower Indus.
325BC = The building of the Indian Ocean fleet, march through the Gedrosian Desert, desertion of the treasurer Harpalus.
324BC = Alexander returns to Persepolis, the Susa mass-marriages, death of Alexanders friend Hephaestion, another Macedonian Mutiny at Opis, reorganisation of the empire....
* Persians & Macedonians receive equal rights
* Military & civilian powers separated in the satrapies
* A unified currency is established (based on silver, with Attic/Greek measurements)
* Greek & Persian exiles are pardoned and encouraged to return.
* Alexander adopts full Persian court ceremony, dress and titles, and is also deified.
323BC = Alexander, now a deeply superstitious semi alcoholic, falls ill in Babylon and dies in June.
As you can see, I have split the above chart into three eras: the Darius period, the Bessus period, and the Spitamenes period (so 3 different leaderheads for the Persians).
Id like to do the same for Alexander: a Macedonian Alexander, a half Persian Alexander, and a full Persian God-like Alexander.
Events Tied to the Map
-----------------------
Now many of the above events can be tied into actions on the map, and dont require linking with the tech tree (all battles & sieges for example).
Other examples:-
Alexander disbands his fleet....we limit his income at the start, so he cant afford to maintain both a large army & a large fleet.
The Gordian Knot....a world wonder to be captured in the city of Gordium.
Darius three peace offers....the Persian AI will handle these as they begin to lose cities.
The Oracle of Ammon in Siwah....another world wonder to be captured.
The Spartan Uprising....the Lacaedomonians start as neutrals, but they might not stay that way.
The Death of Darius....when the Persians enter a new era, they get a new leaderhead.
Persian Mounted Javelinmen....Alexander can always build these, but they require the Persia resource.
Death of Bucephalas....all new cities are called Alexandria except one; Bucephala.
(Alexander may have killed, executed and massacred hundreds of thousands of people....but at least he was nice to his horse.

)
Macedonian Mutiny....a world wonder that makes ALL other wonders obsolete (causing widespread unhappiness).
The Gedrosian Desert.... some units may die if you march through a Sandy Desert (the jungle disease effect).
Death of Alexander....obviously, then end of the scenario (after some 156 monthly turns).
Events Tied to the Tech Tree
-----------------------------
The following DO require entries in the tech tree:-
The Founding of Alexandria(s)....only the Macedonians can have settlers, but they must research to get them.
Allies are Dismissed....some units become obsolete and are replaced by a unit upgrade.
The Persian Successors....again, a new unit type becomes available to the Macedonians.
Persian Cardaces....a new peltast type unit for the Persians, available about 334BC.
Scythe Chariots....available to the Persians about 331BC.
Plus several new stronger Egyptian units, available half way down the tech tree (if Alexander conquers Egypt early in the scenario, then these will never be built).
Ive decided not to bother upgrading the Hypaspists to Argyraspids (their hit points would go down), and Sparta was in decline, so the only Spartan Hoplites they have are those at the start (no more can be built....they build Perioikoi Hoplites instead).
City Improvements and Buildings
---------------------------------
Now then, what to we do about these?
Well, they obviously need to be entries on the tech tree, but trying to link them with events is difficult, and doesnt seem right.
After all, there were NO new inventions during Alexanders short 13 year reign; all those re-named city buildings in that list posted at the top of page three of this thread had existed for many centuries long before young Alexander was a gleam in old Philips eye!
Soooo
..how about this:-
Instead of a Tech Tree, we have a
PETITION TREE.
You as leader receive petitions/requests/appeals/entreaties/applications/pleas....
....and as benefactor/sponsor/patron/supporter/backer....
....you give grants/awards/gifts/bequests/charters/allowances.
So each new item on the tree is not being invented, its just that you have decided to lend your support and permission for that item to be built (be it for the good of the citizens, or the philosophers, or the merchants, or the military).
A ruler may wish to encourage intellectual thought and the arts for example, but he would still have to create the right kind of atmosphere to encourage all the philosophers, poets and sculptors to come to his kingdom....that is what researching the
Petition Tree represents.
Here are some possible examples:-
(Please feel free to make any changes; these are only suggestions)
Foreign Entrepreneurs allows Furnaces? (Coal Plants), or Smithies? (Factories), or Water Mills? (Hydro Plants)....
New Coinage Issued allows City Treasuries? (Banks), or Provincial Mints? (Stock Exchanges)....
New Governors Appointed allows Petition Houses? (Court Houses), or Guard Houses? (Police Stations)....
Patron of the Arts allows Amphitheatres? (Colosseums), or Philosophical Arenas? (Research Labs), or Heroic Eulogies? (Epics)....
Encouraging Trade allows Market Places? (name unchanged), or Warehouses? (Commercial Docks)....
The King becomes Ill allows Apothecaries? (Hospitals), or Military Physicians? (Battlefield Medicine)....
Appeasing the Gods allows Shrines? (Temples), or Temple Complexes? (Cathedrals)....
Sponsoring Learning allows Schools? (Libraries), or Academies? (Universities)....
Support for the Army allows Armouries? (Civil Defence), or Military Discipline & Tactics? (Military Academy & Pentagon)....
And so on.
What do you think?
