Still no Byzantine spawn, even when Greece is dead, and I (Rome) control all of it. Unfortunately, my computer says the saves file doesn't exist, and thus, I can't attach any.
Okay, then there's something else wrong with them. I guess I have to play until 330 AD and see for myself.
So I basically have two suggestions. First make sure more barbs and natives make their way toward Maya. Without that pressure there's really nothing between you and the first 2 UHVs. The second is kind of vague, but I'd like to see some change in the 3rd UHV. I mean it's okay and all, but it's pretty anti-climactic when you crush the Aztecs and discover Europe in the 1400s, which basically ensures the UHV, but you still have to wait through the next 300 years before you get the checkmark. But the first 2 are pretty great, actually, perhaps not quite as much fun as some other small builder civs (Egypt, say), but definitely enjoyable and you really do feel the clock ticking.
Hmm, it's a long time since I played a Maya game for the last time. On the first two goals, did you think the Temple of Kukulkan one was too easy? After all, you're the only one who's able to build it now that it needs corn. It seems better to put a time limit on that one as well, when did you finish it?
And maybe the Mayan UP needs to end a little earlier if you can discover Europe that early

But I agree that even then the UHV only amounts to beating the conquerors and waiting.
I don't particularly like it, either, but it's hard to project the Mayans to get an idea of their "ahistorical" goal. If we find something else, I can make it a "by" goal so you can actively work at making it early.
Very nice. This must put you pretty close to finishing your work on asia, yes?
My to do list is
very short now, yes. The Turks will now get some attention, both of the Ottoman and Seljuk flavor.
How do you plan to keep the Thai's limited, so they don't go crazy expansion in South East Asia? Also what is there UP and UHV'S? IMO perhaps they would have been better as a minor civ, as in reality they did not have that much power, and by the time the Europeans came they were sidelined as a buffer state, between the French and British.
PS. Where is there capital started?
I don't have my gaming laptop, so that is why I will not be able to find these answers out for myself.
I'm answering the questions in reverse order

Their capital is Ayutthaya (later renamed Bangkok), which is 1W of Angkor. That means Angkor gets razed when they spawn (at the beginning I was hesitant to do this, but then I found out it were the Thais who razed Angkor in 1450 so it even makes some sense). To not screw the Khmer over in every game, the Thais only spawn if they're shaky (or unstable if human controlled). This should prevent the existence of a backward Khmer civ in the late game (Thailand researches somewhat faster).
It's right, the Thais weren't much of a military power, but the Kingdom of Ayutthaya and its successors were still the dominating state in South East Asia. Their UHV goals reflect their trade-oriented nature:
- have open borders with 8 civilizations in 1650 AD
- make Ayutthaya the largest city in the world in 1700 AD
- don't allow any foreign power in South Asia* in 1900 AD
*this includes Southern India currently to make it more challenging.
On how to prevent their expansion, I don't see a problem with them regularly controlling Hanoi or something like that. But they don't start with much of an army and even more importantly, they lack the Khmer UP, which means they have no way of going north of Ayutthaya except with elephants which will already limit the AI a lot.
I haven't settled on a UP already. Any ideas? I was thinking of some kind of reverse French UP (which I intend to replace anyway), to represent their good relations with Europe, but Indonesia has a diplomacy related UP already and I don't know if it would make their first goal too easy.
