I do apologise to everbody for taking so long to come back and continue this project, but I'm a bit overworked at the moment with TWO 'special' projects....
(Sorry, but I cannot tell you what they are, as I have signed two non-disclosure contracts, so "mum's the word".

)
I will again be free by the end of August, and I promise that from then on I will totally devote myself to "Alex", with no distractions whatsoever.
Please bear with me.
In the mean time....
Hetairoi22, I did send you my long article about the tech tree on the 19th of July. Perhaps you didn't recieve it.
I hope you don't mind if I demonstrate my comitment to this project by repeating it here, so that others may comment on it.
(Warning....it is a bit long):-
------------------------------------------------------------------------------------
Hello matey.
Here at long last is that stuff about the "Alex the Great" tech tree that I promised.
First of all..I think I was wrong about trying to make a 'Petitions Tree'.
As you know, the idea was to have the 'requests' coming from the bottom up, with things like:-
"Plea from the Peasants"
"Demand from the Army"
"Entreaty from the Philosophers"
....and so on.
This seemed ok at first....but then I began to think about how it would look when trading!
Having the Persians trading techs with say the Indians and offering to swap a "Request from the Town Councillors" for an "Appeal from the Merchants" just doesn't sound right.
I think it would be best to go back to the original idea of having things from the top down (i.e. the King makes decisions about which part of society he/she wishes to develop, rather than the citizens petitioning him).
So, by using the following types of words..
....encouraging/reassuring/calming/inspiring/stimulating/motivating/improving/
advancing/developing/enhancing/increasing/enriching/expanding/supporting/sponsoring/backing/boosting/promoting/advocating
....or....
benefactor/sponsor/patron/support/backing/promoter/guarantor/champion/underwriter/invester/donor/guardian/defender/enthusiast/advocate/devotee/adherent/organiser/developer
....with these words....
....peasants/citizens/merchants/philosophers/artists/army/navy/town councillors/governors/satraps/financiers/entrepreneurs/fishermen/priests/bureaucrats/farmers/nobles/workers/traders
....we get something like this (suggestions only of course):-
City Treasuries (i.e. Banks) = "Supporting the Financiers?", or "Enriching the Satraps?", etc.
Temple Complex (i.e. Cathedrals) = "Boosting the Priesthood?", or "Calming the Peasants?", etc.
Armoury (i.e. Civil Defence) = "Arming the Citizens?", or "Organising the Governors?", etc.
Furnaces (i.e. Coal Plants) = "Improving the Workers?", or "Sponsoring the Entrepreneurs?", etc.
Apothecaries (i.e. Hospitals) = "Advocating Health?", or "Benefactor of the Sick?", etc.
Warehouses (i.e. Commercial Docks) = "Encouraging Trade?", or "Underwriting the Merchants?", etc.
Academy (i.e. Universities) = "Patron of the Arts?", or "Devotee of Philosophy?", etc.
....and so on.
Beginning Techs
--------------------
"Civic Buildings" = allows Water Wells (aqueducts), City Walls (name unchanged), Amphitheatres (colosseums), Petition Houses(courthouses),
Storehouses (granaries), Harbours (name unchanged), Schools (libraries),
Marketplaces (name unchanged), Shrines (temples),
the ability to form "Embassies", "Rights of Passage" and "Alliances".
(All civs, except the Scythians, begin the scenario with this tech)
"Nomadic Lifestyle" = allows Wooden Palisades (another type of city wall),
Shaman's Tent (another type of temple), Leader's Tent (another type of courthouse), Storage Pits (another type of granary), Tribal Leadership (a renamed Despotism Government).
(Only the Scythians have this tech at the beginning)
I only want the Macedonians & Lacedaemonians to be able to build "Training Grounds" (i.e. Barracks), and they can do so from the start.
Events Tied to the Map (so are not on the tech tree)
---------------------------
Now many of the above events can be tied into actions on the map, and don't 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 can't 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'.
"Macedonian Mutiny"....a world wonder that makes ALL other wonders obsolete (causing widespread unhappiness). Comes late in the tree.
"The Gedrosian Desert".... some units may die in a 'Sandy Desert' (the jungle disease effect).
"Death of Alexander"..obviously, then end of the scenario (after some 156 monthly turns).
The Full City Improvement List
--------------------------------------
Aqueduct = Water wells....at start.
Bank = City Treasury
Barracks = Training Ground (example: Campus Martius outside Rome)
Cathedral = Temple Complex
City Walls = (unchanged)....at start.
Civil Defence = Armoury
Coal Plant = Furnace
Coastal Fortress = Sea Defences
Colosseum = Amphitheatre....at start.
Commercial Dock = Warehouses
Court House = Petition House....at start.
Factory = Smithy
Granary = (unchanged....or maybe Storehouse?)....at start.
Harbour = (unchanged)....at start.
Hospital = Apothecary
Hydro Plant = Water Mill
Library = School....at start.
Manufacturing Plant = Workshop
Marketplace = (unchanged)....at start.
Offshore Platform = Salt Works....I don't like this one, maybe leave it out.
Police Station = Guard House
Research Lab = Philosophical Arena
Stock Exchange = Provincial Mint (unlikely to be one in every city)
Temple = Shrine (so that it doesn't get confused with Temple Complex)....at start.
University = Academy
---------------------------
Heroic Epic = Heroic Eulogies (increases the likelihood of leaders)...."Patron of the Arts" maybe?
Iron Works = Slave Market (doubles output in one city)
Forbidden Palace = New Imperial Capital (only Alexander needs this)
Wall Street = Imperial Bureaucracy (requires 5 Provincial Mints)
Military Academy = Military Discipline (the troops stay in formation without a leader's charisma)
Pentagon = Military Tactics (Alexander was the first Greek to have a reserve, at Gaugamela)
Intelligence Agency = The King's Eye ("....I'll be watching you...."

)
Battlefield Medicine = Military Physicians (available with the "King Becomes Ill" tech event during the 1st 'Era' perhaps?)
---------------------------
WORLD WONDERS (almost all of them, except the "Macedonian Mutiny", are already on the map at the start)
------------------------------
Other advances and abilities:-
The ability to have road movement across rivers (i.e. bridges)....
The ability to double the effect of wealth (i.e. economics)....
....plus some other abilities that I have forgotten about!
(Trees cannot be chopped down, so there is no real need to have the "Plant Forest" ability. And I don't want Fortresses being built all over the place.
Likewise, the "Trade over Seas & Oceans" ability is not required, because all regions are 'economically isolated' from each other.
I'm in two minds about the "Draft" & "Protection Pact" abilities that come with a (renamed) Nationalism. It would be nice to have the Persians with this ability, so that they can raise huge armies of poor quality troops and form grand alliances against Alexander....thus keeping him at war with someone or other.
Maybe we could include it as an 'at start' tech for the Persians)
-------------------------------
Governments:-
----------------
Scythians = a renamed Despotism at start (i.e. "Tribal Leadership").
Persians = a renamed Monarchy at start (i.e. "King of Kings").
Macedonians = a renamed Republic at start (i.e. "King of Macedon").
Greeks & Sparta = another renamed Monarchy at start(i.e. "Oligarchy").
The Egyptians/Arabs/Indians = another weak renamed government (i.e. "Local or Petty Tyrants" perhaps?).
Soooo...no changing of governments during the scenario.
How Do All The Techs Link To Each Other?
-----------------------------------------------------
Obviously, some follow-on after others:-
Schools (Libraries) --> Academies (Universities) --> Philosophical Arenas (Research Labs)
Marketplaces (name unchanged) --> City Treasuries (Banks) --> Provincial Mints (Stock Exchanges)
Smithies (Factories) --> Furnaces (Coal Plants) & Water Mills (Hydro Plants) --> Workshops (Manufacturing Plants)
As there will be three 'Eras' (the Darius/Macedonian-Alexander period, the Bessus/Persian-Alexander period, and the Spitamenes/God-like-Alexander period), I therefore suggest that we also spit the various advancements likewise.
(This is how the original game is organised, with early Ancient
advancements, Middle Age advancements, and later Industrial Age advancements)
Events Tied to the Tech Tree (these DO require entries)
-----------------------------
The following DO require entries in the tech tree, but what to call them, that's the problem:-
"??????"....only the Macedonians can have settlers, but they must research to get them (at the end of the first 'Era'). I can't think of anything for the Persians from this tech advance.
"Allies are Dismissed"....some Macedonian units become obsolete and arereplaced by "Persian Successor" javelin horseman, and something similar for the Persians (in the second 'Era').
"Military Reforms"..a new peltast type unit called "Cardaces" for the Persians, available about 334BC, and Alexander can now recruit "Hired Hoplites" (midway in the first era).
"Scythe Chariots"....a unit available to the Persians about 331BC (at the endof the first 'Era').
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).
I've 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).
Whew! See, I said that I wouldn't be able to send this as a PM! Ha, ha, ha.
I hope it gives you a bit more of a guideline.
And don't worry too much about the details....once we have even a rough working structure, we can always tweak it later.
"I'll leave it with you".
All the best (from a very thankful).....Kryten.
