Hi!
Philosophy:
It should grant a Modern/industrial tech(like Demosthenes or Democrithos, who somehow deducted that everything is made of atoms[non-divedables]).
Chitizen Itca: Slaves work as fast as normal worker(they fear, that they would be sacraficed).
Ancient Olimpics: Like UN in CIV II.
Tech: Standardization: -5% or -10% unit shield cost, -25% upgrade.
Tech: Martial Arts(or similar) citizens can defend cities(at a VERY BAD Defense[1/2* worst buildable military-unit?]??? Don't know if this won't unbalance the game.
Couldbe called 'Volkstrum'.
Tech: Religious Reformation(Luther). +1 citizen/ city made content.
Nation: Byzanthium: UU: Khlibanophoros(ultra-heavy knight, not sure if this is the right spelling), not a fast unit

.
Wonder: China Silk Trade Route (from Currency to Caravell/magnetism/navigation).
Giant Palace at Samara:
Doubles Cultural Output of the city, but cost 15 GPT
(the palace was 1,56 km^2[~0,61 sqmiles], at its top the city reached pop:100.000, fifty years later pop:15.000.

.
New nation: Jews.
Religios & Commercial(UU:Settler/worker that has 1 defense).
Or
Militaristic & (Commercial or Religious)
UU:mosad agent.
Special ability: twice the normal time(half probability) for conversion.
Ability: Agricultural: gives food on mountains(Inca, Japan, China).
Japan Could be Agricultura(not that important). Japan should begind with warrior code(bushido).
Europe:
Luxuries
There should be Grapes in:
France(around Aquitania, Poutoi[??], Champagne ).
Italy(Sicily, Toscana)
Hungary
Hispania(Around Toledo)
Furs: Novgorod
Ivory: Around Alexandria.
Gem's: Don't know

.
Spices: Well Transylvania had Salt(Extrem masses, along with Gold, those were in Slovak Republic[called: Felvidék~highland, upland] too), don't know if Salt is considered as Spice.
And Hungary(not nowadays, but the historical[region: today's Hungary+Transylvania+Slovak Republic+Burgerland[a little from Austria]+Slovenia[Dalmatia]+Croatia+South Western Part of Ukraine[from the borders to Carpathia]+Roughly the half of Serbia[Belgrad was an imortant Castle at South of Hungary, called 'Nándorfehérvár'<fehérvár = belgrad=white castle>]) was a "Great Marsh", mostly the Western part. That is why Germans(Teutons) couldn't conquer Hungary, becacuse they couldn't use their knights on the Marshes in the begining.
Later on King Matthias of the Hungarians(aka Matthias Corvinus, just like Corvinus in movie: Underworld) conquered Wien and Bratislava in the XV. century.
Sorry, if this seems to be "the Glorious Historical Hungary", but I felt important to correct some things.
That's all.
