GRECKO-PERSIAN WARS

The civs are as follows:
Athens/Paricles
Sparta/Leonidas
Persia/Xerxes
Egypt
Indus River India/Porus
Arab Nomads (Probably almost impossible to even survive very long with)
Massagetai/Tomyris
Turkish Nomads
Deep India/Asoka

The target historical time frame is around 490 BC, though the scenario is set to start at 500 BC. If played all the way out it should be about 437 BC or so (assuming it works correctly).
Several of the civ leaders obviously don't match up time-wise, but this shouldn't be a big deal. I'm aware Mecca wasn't even
founded for a very long time and also that Greece was not nearly as allied in 490 BC as it is at the scenario's start. 
It doesn't seem to be definitively known where exactly turks originated, so I thought they were a nice nomad 
group to add in.

The scenario is modded to be played on Standard game speed, so playing on a different 1 will either not work or just won't work as intended.
Research is slower than normal (~100-300% more costly depending on the tech) & great scientists have had their free tech ability removed.
Libraries/Paper Makers/Universities provide a small amount of culture now. The idea behind the tech cost increase is to keep the ancient/classical units useful fairly deep into the scenario.
Many techs have been made overwhelmingly costly. This should effectively end the tech tree early in the Renaissance era.
Also, research agreements take 60 turns to bear fruit. This is important to know, as you don't want to waste the large science boost you get from them when the deal ending turn finally arrives.

As for wonders, all civs have their historical wonders plus:
Athens has stonehedge
Sparta has the great wall
Persia has the forbidden palace
Indus River India has Manchu Pichu

Oxford University, The Porcelain Tower, Himeji Castle, and the Kremlin are all removed from the game. The Great Library has been changed so that it no longer gives a free tech. It has higher culture and great scientist points to make for this.

To keep unhappiness from getting out of hand colosseums/theatres have been bumped up by 1 each in terms of happiness provided.
Natural wonders are also placed at various spots on the map to help with happiness as well. Preplacing the Forbidden Palace has the same idea behind it.

There are 2 potential issues with getting the scenario to work upon download.

1.Map won't show up in game setup screen.

I experience this myself when I try to download scenarios. The fix is easy luckily. Simply manually move the map
file from the "Mods" folder into the "Maps" folder yourself. If you can't find these, my mods folder is located under
documents/my games/civ 5/MODS. My maps folders is located in the same path.

2.You can only play as Persia.

This is a known bug introduced by the latest civ 5 patch. Firaxis support has provided a fix ITT on civfanatics:

Additional Changes version 5:
-Changed preplaced libraries to curb Persia's research progress advantage & remove a misplaced 1
-Removed Hoplite/Immortal upgrade to Pikeman
-Decreased Persian territory in the Iraqi/Arabian Desert
-Decreased Spartan/Athenian territories slightly
-Increased research cost of most techs
-Lengthened research agreements (60 turns)
-Added a sea invasion point from the Pellopenisian into North Africa
-Buffed starting militaries/defenses for all the small empires/gave Macedon Cavalry & Athenian Catapult enough xp for their 4th promotion
-Gave all small empires some additional starting policies to start with
-Buffed War Elephant combat strength
-Increased territory of some of the small empires
-Made Autocracy policies accessible during the Renaissance
-Persia is now set at permanent war with everyone 
(otherwise the lesser civs were just sueing for a lopsided peace agreement immediately after war had started)
