Right, the map's been cropped, most things (techs, units, improvements/wonders) have been deleted (temporarily), and everything seems to be running fine, in game, as there is no lag! I think the problem was due to the massive amount of resources on the map...
Now, I've decided on some of the victory conditions, and I think the civs, for the time being at least, so here's a rundown on how some things are going to work:
Mycenae - The Trojan War
Civs: Mycenae
The victory condition here sees a welcome return of the original victory condition planned for Mycenae. They must return the Trojan Horse to a victory condition - either at Troy or Jerusalem, although since they are in a locked war against Troy, they will naturally be pushed into taking it there. The Mycenaeans will suffer the most out of any Greek states during the Doric invasion - a resource will spawn in Mycenae which will make everyone want to attack the civ (thanks for the ideas, everyone

). The tech tree for Eras 2-4 for Mycenae will be the Peloponnesian League tech tree, although the particular tech which allows the building of the League (and thus the League victory) will be hidden from Mycenae.
Troy - The Trojan War
Civs: Phrygia (Troy)
Troy also goes back to the original VC which they had at from the onset of development. For Troy, you win the game by simply keeping a garrison inside its city. Simple enough. However, the locked alliance against Mycenae will undoubtedly come back to haunt you at various times. You could speed up the victory process by capturing the Trojan Horse - although as the player, that will almost undoubtedly mean having to take the Peloponnesian possessions away from Mycenae to find where they've hidden it! In eras 2-4, Troy will be able to research the Raiding tech tree, with its own Phrygian flavour.
The Peloponnesian League
Civs: Sparta, Corinth, Thebes (with Mycenae also able to research most techs)
These guys will work pretty much as they did before, where you have to research the majority of the tech tree, build the wonder, and hope for the best. Some good units will be available for the Peloponnesian civs, too.
Athens
Again, Athens will work as pretty much normal, except their first era will be tied in to most of the other Greek states' trees, too. From era 2 onwards, they have to work pretty much on their own in their tech tree, but they'll be able to build some powerful culture-producing wonders in their capital, which should catapult them towards a single-city culture victory! They'll also be able to field a powerful navy.
The Quest For The Golden Fleece
Civs: Argos, Thessaly, Phoenicia, Euboea, Ionia, Magna Graecia, The Bosporan Kingdom, Lydia, Iberia
By far the biggest VC in the game! Civilizations in this VC will be able to build the only ocean-faring transport, which they'll need to be able to capture the Golden Fleece! They can bring it back to either Troy or Jerusalem, whichever is easiest, really. After the first era, I'm thinking of allowing them a SS victory whereby they can must build up a colony.
The Minoans
Civs: Crete
Victory for Crete can come in two forms. The first, is set during the first era, where they can build some special units who can enslave defeated units, turning them into sacrificial offerings, enough of which can grant them a culture victory! In eras 2-4, they'll have the same SS-possibility as the GF civs above, and they will share a tech tree, too.
Dominating the World - The Armies of Ancient Mesopotamia
Civs: Babylon, Assyria, Hatti, Persia, Kolchis
For these civs, the game will be about building as large an empire possible. Obviously, some things may hamper success. For example, Babylon and Assyria are in a locked alliance. The governments initially will work heavily against expansion. And other such stuff. However, eventually, these civs will be able to expand hard and fast, and these are pretty much the only civilizations capable of utilizing "foreign" resources, allowing for some pretty diverse armies. Babylon may also be able to build many cultural improvements/wonders, to rival Athens' VC, although I'm not 100% decided, yet.
The Arc of Covenant
Civs: Ethiopia
For Ethiopia, victory will come by taking the Arc of Covenant (correct me if I'm thinking of the wrong relic, although I think it's the right one) back to a VPL, aka either Jerusalem or Troy. However, Jerusalem will be strongly advised if you could make it there. Getting there will be the hard part. You'll only be able to get onto the high seas required to get back to either Jerusalem or Troy in the latter part of the game, so throughout most of the game, you'll be stuck in the bottom of the map, playing the waiting game. You'll be able to build some pretty awesome units, though, to pass the time! These will mostly be used against your local rivals, which will be Egypt in Africa and Babylon in Arabia.
Macedonian Conquests
Civs: Macedonia, Epirus
For Macedonia and Epirus, you'll have to wait until late-game, where you will be able to use the most powerful units in the entire game to dominate the world! I'm thinking of maybe "morphing" their tech tree with the P League tree, but like with Mycenae, disallowing their building of the wonder, and therefore excluding them from that victory condition.
Egypt
Civs: Egypt
Egypt will be able to win an empire-wide culture victory, if they play their cards right! However, perils will face them, especially if they want to keep hold of Palestine! They can also win via a VPL victory, as they control Jerusalem, although this will be unlikely as the Mesopotamian civilizations will undoubtedly take the city at one point. One of them major downsides with Egypt is that they won't be able to build many good units in Mesopotamian lands; they'll have to rely on naval imports from Egypt!
Raiding Barbarians
Civs: Scythia, Thrace, Dacia, Etruria, Celts, (Phrygia)
For the "Raiding" civs (apart from Phrygia), you won't really be able to "win" the game as such, but you will be able to have fun harassing the other civs with Hidden Nationality units!
This should just leave India. I don't know what I'm going to do with these guys yet. Anyone have any suggestions?
