Leoreth, I know that you might not be giving your whole attention to the Americas yet, but I!ve been waiting for something like this for a long time so I really couldn't help myself and had to give you some ideas =D
I think that for the modern independent nations of the new world (ie, mexico, brazil, etc) you shouldn't make their spawn dependent on previous colonization. I understand that you may want to define some spawns as conditional, but I think that in low civ density areas (like the Americas) that's not the best option. Another cool idea would be to let the human player spawn only with the capital and have him/her conquer his way to full independence as the 1st UHV.
Regarding Mexico and Peru/Colombia, I wouldn't mind seeing the Aztecs "evolve" into Mexico, specially if they have lagged behind in tech/score or are unstable. Same could apply for the Incas.
About Brazil, I think that jungles should have a different effect for them, Brazil doesn't have that many cities IN the amazon forest and they have done a lot of deforestation to get agricultural and pastoral land. Actually, I'd even suggest an ecologically-related 3rd UHV for Brazil. Although I do like the three ones that soul-breathing suggested, apart from the limitation of building the wonders specifically in Rio, if most of the American countries are spawning by themselves, then UHV2 wouldn't be much of a challenge.
Regarding Argentina, here are some UHV suggestions:
UHV1: Export X number of food resources (cattle or cereals) by 1900, either for gold or for other non-food resources.
UHV2: Have the most industrialized economy in the world by 1950, or, alternatively, the highest GDP.
UHV3: (Haven't thought of this one yet...)
In any case, if there are any Brazilians or Argentinians reading this, I'd say they would be the best to point out what their countries' most important feats and challenges are.
Regarding Mexico (and as the Mexican I am) here's a suggestion:
Important notes:
- You should spawn a horse and an iron resource for them (The iron should either be immediately north of Mexico City or on the northeastern part, near the Gulf).
- The Americans should be aggressive, at least during the XIX century.
- Mexico should spawn with Catholicism as state religion and with a missionary.
- At least one of the mountain tiles in the Pacific coast should be turned to hills.
- The Aztecs' and Mayan's last UHVs should be moved earlier so that they can be achieved before Mexico's spawn.
Spawn date: 1810 (declaration of independence).
Spawn/Flip area: All of modern Mexico, southwestern USA (Texas, California, New Mexico, Arizona, Nevada, Utah, western Colorado) and Central America down to Costa Rica (not Panama). (
http://en.wikipedia.org/wiki/First_Mexican_Empire)
Unstable areas: Texas (but not the other US States I mentioned) and Central America from (Guatemala to Costa Rica).
LH: Hidalgo (

http://forums.civfanatics.com/downloads.php?do=file&id=14218).
UU: A modified Rifleman or some late 1800's unit. You could call them "Revolucionario", "Insurgente" or something of the like, I can't think of other names.
UB: A Lienzo Charro (
http://en.wikipedia.org/wiki/Lienzo_charro), that could replace either the theatre or the stadium, is the only building I can think of so far. It should require horse or at least some other animal resource. The building should give a stability bonus, in addition to the culture bonus it normally gives.
UP: (Name?) - Cities with Catholicism get a special bonus (culture? production?) even if there is no state religion.
UHV1: Make Mexico City the largest and most cultured city in the world by 1970.
UHV2: Establish an embassy with every other civ and achieve a friendly/polite attitude from at least 70% (or X%) of world leaders by 2000.
UHV3: Maintain territorial integrity, either until 2000 or, preferably, until the last turn. This means not losing any cities, wherever they are, because of conquests or instability AND not allowing any foreign cities in the spawn area (ie: settle the area if it hadn't been settled).
Here's a justification for my proposals:
- The first UHV is quite straightforward, Mexico City is one of the largest cities of the world and, on some counts, the largest one for a long time in the late XXth Century. The cultural part represents the country's cultural diversity and artistic history.
- The 2nd UHV stems from the country's long history of peaceful diplomacy and non-intervention policy. During the XXth Century, Mexico's foreign policy has been to accept sovereignty of all other states (dictatorships included), to not doing any military interventions and to grant asylum to any refugees that ask for it. Also, Mexico has more free trade agreements than any other country. The UP should help with this goal, as having no state religion could be a way to improve relations, yet as Mexico starts with Catholicism the anarchy should make it a challenge for the 3rd UHV. This anarchy perfectly represents the Reform Wars of the XIXth Century, so it's all historical =). The embassy/attitude UHV is, IMO, a good way to represent all of this. (
http://en.wikipedia.org/wiki/Foreign_relations_of_Mexico).
- Finally, the 3rd UHV represents Mexico's most painful (and still regretted) event, the loss of half of the territory. Mexico lost all of Central America a couple of years after independence from Spain, as all of those countries asked for their own independence. Texas also declared independence and that started the Mexican-American war that ended up with the loss of the modern southwestern USA. Mexico also received a couple of French invasions and other territories also declared independence at different points in history, although, unsuccessfully. The instability of Central America and Texas and specially the aggressive attitude of the more scientifically and militarily advanced US should make this 3rd UHV hard to achieve. On the side of the US, getting this territory through war and not settling empty land is also more historical and interesting.
so... what do you think??
