Spend one eco point on Military, the other on infrastructure. (those mercahants need two things protection and a system to move trade goods)
ok Culture and such stuff.
Create rubber from mixing the latex from Castilla elastica (a type of rubber tree) and The juice of a local vine, Ipomoea alba. This creates Rubber. This will be used in the creation of Rubber balls for the ball game of the Olmecs.
Olmec Art
Create Highly naturlastic art, again creating more jade statues of the Divine Jaguar, but don't forget the other local creatures too. Bird Figurines and so on.
Huge Giant Statues of people are to be built at crossroads and other meeting points. These will depict a very high accuracy in regard to Anatomical features. They will have however a slightly larger helmeted head.
The Olmec Rubber ball game
As might be expected with a game played over so long a timespan, details of the games varied over time and place, so the Olmec ballgame might be more accurately seen as a family of related games. Some versions were played between two individuals, others between 2 teams of players.
The games shared the characteristics of being played with a hard rubber ball in a sunken or walled linear court, sometimes with perpendiculars at the ends.
Across Olmec, ball courts were built and used for many generations, and their shapes and sizes do vary. Some sites had multiple ball courts, but others had only one. In some parts of Olmec ballcourts are found in most or all sizable population centres, while in other parts they are less common.
While the game was played casually for simple recreation, including by children for play, the game also had important ritual aspects, and major formal ballgames would be held as ritual events. The game between competing teams of players could symbolize the battles between the gods in the sky and the lords of the underworld. The ball could symbolize the sun.
Ok I have kept some of my research material back for later use.
Expand into Zaptoec Land, Since they are already growing as a civilisation on similar lines to mine, the extra boost given by our rule over there cities and lands should make it a LOT easier. (we compliment each other).
