I have a confession to make. I'm hopelessly addictied to this mod. I appreciate the amount of time and effort you took into creating it. I'm not into the randomly generated maps anymore. I used to play the Test of Time mod but that thing is really a resource hog and becomes completely unplayable at around the middle ages and remains that way for the rest of the game. You've accomplished the fastest loading world map mod. I'm using an AMD XP 1800 with 2 GB of RAM. I can complete a game in 1/3 the time that I could on the Test of Time mod (around 20 hours versus the 60 hours for the other map). My compliments to the new terrain and the modifications to the existing ones.
I've been playing random nationalities so far. The first game I played as the Chinese. I coerced the Koreans and Mongols out of their techs before quickly eliminating them. Then I noticed Japan was settling in the lower mainland of China which I had to eradicate. Our relationship remained sour for the rest of the game. The jungles and mountains provided a nice barrier but also prohibited my expansion. I made the grave mistake of switching to a Feudalistic government without realizing how it would cripple my empire. It wasn't until I learned Communisim that I recovered from this. I ended up losing the game to the Arabs in due to their high culture. One of the things I noticed in this game was that the Arabs had bombers in the late 1400s which I thought wasn't supposed to happen.
The next game I played was with the Babylonians. This game lasted about 20 minutes after my failed strike on Sumeria. The Arabs declared war on me a few turns later and I couldn't keep up.
The following game was really interesting. I played as Rome and conquered the globe on turn 2049. My best unit was the Cavalry. The 8 turn minimum research time really crippled me from advancing but my military was unstoppable. I ended up building the Holy War, Knights Templar, and the Statue of Zeus which really helped to crush the European opposition. I would like to mention something to the fella who says you need Ivory to build it. You can either contact the Indians and trade for it or conquer Carthage. There is Ivory close to Rome which makes this possible. I also noticed in this game that I couldn't build the Suez Canal which meant my navy had to go around the Horn to strike at the Far East.
The last game I played as the Persians and it was by far the most fun I've had at civ in a long time. I got lucky and found a settler on the goody hut near Turkey early on. I was going to complain that the Immortal has been reduced to a Spearman but noticed that the shield cost is half. I'm not sure I agree with it 100% but I didn't need them for very long anyway. The Arabs and Babylonia declared war on me almost immediately after I got the free settler. Sumeria didn't want to let me move through their territory so I eliminated them with the force I was sending to Arabia. Babylon must have panicked and sued for peace immediately. I accepted their terms but declared war on them as soon as the Arabs were eliminated. I noticed the Ottomans only had 3 cities so I decided to take care of them because I've seen what the Sipahi can do. Egypt ony had two cities and fell right after that. By this time the middle ages had rolled around and I built up my Knights. I noticed that India was developing slowly and crushed them before they could build the War Elephants. Now my empire was huge and the effects of corruption set in. The Europeans were advancing quickly in the tech area so I decided to dig in and hold out for the industrial age. I knew I was sitting on the gold mine with all the resources that I would need. I generated a lot of income from the Europeans by selling my incense to them. It was interesting to watch Spain rise to power and colonize South America and the Gold Coast. The game really got hairy when everyone learned Nationalism during the late 1800s. The whole world erupted into a series of wars which was really cool to sit on the sidelines and watch them beat on each other. Spain was reduced into a size of what it is today and Germany gained a lot of power. I was about two techs behind Germany and England and it was looking bleak for me. I missed building the Theory of Evolution by one turn which would have put me right back into it. I switched my government to Facisim to get the worker bonuses and prepare for an all out war. England tried to plant a spy on me and I got ticked. No one would sign an alliance which furthered my anger. I've never been successful planting spys before this game. I took the gamble and got one in England. Now I began to sabotage production and steal tech from her.

Germany got very upset when I got caught spying and declared war on me. I called favors on all the civs which I was being nice to for the whole game to help and they came to my rescue. A few turns later I finished the UN and was voted in almost unanimously.
I started a game as the Americans but I don't think they really belong in this mod for the following reasons. North America is an extremely resource rich continent and on this map it is way too small. You've also got marsh where Virginia and the Carolinas are which is higly innacurate. Those are tobbaco rich areas with lots of farmland. My suggestion would be to get rid of the Americans altogether. After all, America was created by the Europeans and as it is set up now, there really isn't a way for them to develop into a Super Power. So far, I've eliminated the Iroquois because they wouldn't trade tech with me and spent the whole time fighting barbarians. There isn't one single horse resource in America (I'm aware that they weren't here until Europe arrived), but the Americans defeated the Indians with the Cavalry. By the time America makes contact with Europe it is way behind on the learning curve which makes the end game unrealistic as far as tech goes. It's around 1400 and I just learned Chivalry and Invention. Europe will be here in a couple 100 years and in entering the Industrial age before I'm halfway done with the middle ages. There is a slim chance of getting into the game at that point. Most AI civs are reluctant to part with their precious technology and I'm a sitting duck for a number of large scale invasions.
I would replace America (keep in mind that I'm American) with a Plains Indians tribe with the mouted warriors to keep the Iroquois and Aztecs in check. You could cripple them further so they're not too strong when the Europeans arrive.
I think this mod is way too easy if you have a civ in or close to Europe and too hard if you start far away from it. I would prefer it to be challenging no matter which nation I start with. Berlin has the best starting spot and always grows huge. I really think they have a good advantage being Scientific and Miliarious. I'm not sure what you can do to balance that out. Maybe make techs not tradeable. 90% of the time the AI won't trade it with you unless they get an advantage but they'll trade it freely amongst themselves.
Anyone can argue the inclusion or exclusion of certain civilizations because of the nature of the game. In all reality, northern Europe didn't really exist as civilized nations until the late middle ages and by that time the great civilizations of the middle east had already peaked. It's too bad that there isn't a way to simulate that on a world map.
I'm going to download the new version and start plahing it right away. Despite any of the small shortcomings, this mod is top notch and a lot of FUN to play.
