On the other hand,
Poland is 12 tiles away and has access to:
1 x gold
3 x salt
1 x marble
1 x truffle
in an area of 10x10 around his capital.
he has no immediate neighbours and has plenty of territory to expand to 6 or more cities. He doesn't need to trade truffles with me to expand.
Yes, diversity of resources would match how fast the AI is willing and able to found in my games, and it's not map type dependent, but RNG of the map script generator. This is also in the base game. As the human I know exactly how to play a low diversity resource happiness start. (It's in fact one of the things that Tradition is better at.) The AI though has to wait for happiness buildings to be constructed.
This is mostly because the AI is slow to connect SPARE copies of luxaries, so a real solution would have to be at that level. We know that that it's really good about getting the first copy so basically the C++ change could be to remove whatever if/else logic there is about is that luxury type already connected and just always treat it when setting work priorities as if it doesn't have any connected.
The other possible thing to look at would be the LUA script level that generates these map scripts and try to find out why in some map regions it places 3 or 4 unique luxury types and in others it doesn't place any.
I have the feeling that part of AI Maya's problems is that very few luxury types are allowed to be in Jungle (in addition to how long it takes to clear the jungle to get to the resources.)
For a short term XML fix, I'm seeing a couple of possibilities:
1. For the Circus, remove all resource requirements but add 1 gold maintenance. This building (and Stone Works) is currently the only ancient era building available that gives happiness bonuses.
OR
2. Move the Colosseum up from the Classical era to one of the Ancient Era techs. But which one?
(Both would be overkill and so to be avoided)
I'm more inclined towards the first solution on making Circuses available everywhere (but with a 1 GPT maintenance cost) as a stop gap measure until it can be taught to speed up spare luxury connections.

Turn 215 Beginning of the modern era update:
Major events during the Industrial era
The French & Mayan war is now over. It doesn't appear any cities exchanged hands, but pre-war France colonized the NE part of the Mayan home land mass (from city name).
Mayas caught up with the rest in the world in science.
Austria married their two city state allies. With one of them being the only city state that started within 2 hexes of AL, that's somewhat annoying. Austria & France are now at war, but no cities have changed hands. They also have the most culture for me to overcome.
England & Mongols are still at war, no additional cities have changed hands.
Portugal has allied itself with almost all remaining city states (could be after a diplomatic victory.) While Austria continues to host for now, Portugal is almost a shoe in to take control of the world council when it expands its infrastructure.
England built both PT & the Louvre.
The Netherlands piety start continues to keep their cities claimed land tiles far behind that of those picking either Tradition or Liberty.
I was first to modern era via Oxford Radio but I suspect the AIs will join me very quickly. Things are still looking good for my planned cultural victory. However, it's looking unlikely that I'll be able to propose anything during the 3rd regular council.
Me: 45 techs. Land score 63. #1 population & approval
Austria: 48 techs. Land score 88. #1 in everything else
Portugal: 46 techs. Land score 47.
Netherlands: 44 techs. Land score 29. Worst GNP & troops
Maya: 45 techs. Land score 23. Worst population & crops
France: 46 techs. Land score 53.
Mongolia: 44 techs. Land score 28. Worst in everything else
England: 48 techs. Land score 61
Edit:
Turn 243 Beginning of the atomic era update:
During the modern era, the world divided into two games, Order vs Freedom. (No one picked Autocracy) Lots of ideological wars and those not in actual wars with different ideologies have denounced each other.
Austria captured Mongolia's western city on their home landmass.
I started the era by using a faith based GE to rush Effiel Tower.
Austria built Statue of Liberty before I reached the tech.
England build Broadway before I could find a good time to start it.
Me: 57 techs.
Atomic Era 65 land area. #1 population & approval. Freedom +34 happiness
Austria: 60 techs.
Atomic Era 106 land area. #1 in every other category. Freedom +11 happiness
Portugal: 58 techs.
Modern Era 51 land area. Order with Civil Resistance. +22 happiness
Netherlands: 56 techs.
Modern Era 31 land area. Freedom +21 happiness
Maya: 57 techs.
Modern Era 27 land area. Worst population & crops. Freedom +15 happiness
France: 57 techs.
Modern Era 59 land area. Order with Civil Resistance. +3 happiness
Mongolia: 55 techs.
Modern Era 23 land area. Worst in the rest. Order with Civil Resistance. +16 happiness
England: 58 techs.
Modern Era 81 land area. Worst approval. Order with Civil Resistance. -4 happiness
I'm influential over 3 of 7, still looking good for my cultural victory but it may be a race to complete this before someone (most likely Austria) builds the spaceship.
Atomic Era newsflashes
On Turn 247 Austria captured the Mongolian capital on their turn while Portugal captured the Mayan capital on theirs. Both of the civs who lost their capital are down to 1 city, Mongolia is in fact completely off its starting landmass.
World Ideology of Freedom passed, upgrading all resistance to Order ideology civs from Civil Resistance to Revoluntary Wave.
England promptly revolted to Freedom.
On Turn 255 Portugal captured Mayas last city, eliminating the Mayas from the game. This cancelled an RA that I had signed prior to that war breaking out that was going to come due in 5 turns.
I'm now influential over 2 of 6.
On Turn 266 France & Mongolia DOWed me. This actually preempted my planned Netherlands + mine attack on France by a few turns. (The Netherlands would still follow thru and DOW France on the original planned turn)
On Turn 267 Portugal DOWed me.
On Turn 270, England captured the last Mongolia city, this is the
second major to be wiped out in the game. I'm now influential over 1 of 5 civs.
Portugal's fleet started arriving this turn. Hey, your force wasn't supposed to come from that direction. I issue an emergency recall of my forces attacking France to defend my homeland.
Turn 272
Beginning of Information Era status. I entered it via the standard one allowing National Vistor Center when seeking Cultural victory.
Austria completed the Great Firewall, but that's no big deal since they've adopted Freedom. If it had been Portugal, that would have been a problem to my victory.
The Olympics project just started. Hopefully Portugal doesn't boycott them when they start.
I'm now actually dead last in number of techs, but this doesn't really matter for my victory since I'm only one tech away from the Internet. This does however mean my Privateers are quite a bit outdated.
Austria has made significant progress in the war against Austria. A minor problem for them is that they've now taken the easy ones via sea. Going by sea they'd actually have to target the one furthest away from them and come in that way. (Paris is behind a deep cove, protected by another city in that direction, in turn protected by an city on an island.)
It may be easier for them to expand by land to take Paris even with the rough terrain.
Egypt: 59 techs. land area 68. #1 pop & approval. Last in science. Freedom +30
Austria: 63 techs. land area 136. #1 in everything else. Freedom +14
Portugal: 62 techs. land area 71. Worst approval. Order with civil resistance -2
Netherlands: 61 techs. land area 36. Worst pop, crops, man goods, and land. Freedom +34
France: 62 techs. land area 44. Worst GNP & troops. Order with Revolutionary Wave +8.
England: 64 techs. land area 98. #1 science
Current time to victory is still infinity, but will get much better once the Olympics start and Internet is completed.
These ongoing ideological wars may give me more time to win by culture prior to spaceship launch than the AI tech progress suggests by diverting the AIs energies into these wars.
Edit:
Information Era update (thru end of the French war)
I indeed started hosted the World Games.
Austria captured the French city west of the French capital.
It took a few turns, but I drove off Portugal's invasion force. It was under strength, but Portugal is at war with other civs at the same time (and so was I)
I inflicted enough damage to the French island city that once they were willing to talk, he ceded the city to me for peace.
I have a Great Musician with naval escorts now on the way to Portugal, who are the only civ I'm not yet influential over.
Edit:
And the end of the game update
Turn 295: Austria captures Paris and signs a peace treaty. (Effectively forcing France into an involuntary peace treaty.
Turn 297: Portugal will finally talk. Straight peace signed.
Turn 299: I become influential over Portugal and win.
Most advanced AIs towards science victory built 2 parts.
