https://en.wikipedia.org/wiki/Collared_peccary This is the closest thing to a wild boar in the Americas. It's not just for Mesoamerica.       Canis latrans is other which was not taken into account the first time. This is because its habitat is not well documented, and no one associates this animal with the Mayan world. https://en.wikipedia.org/wiki/Coyote This animal is more culturally associated with arid zones, such as Aridoamerica. "The coyote is a prominent character in Native American folklore, mainly in Aridoamerica, usually depicted as a trickster that alternately assumes the form of an actual coyote or a man. As with other trickster figures, the coyote uses deception and humor to rebel against social conventions. The animal was especially respected in Mesoamerican cosmology as a symbol of military might."   A third one I found is a rabbit that is found in North and Central America. https://en.wikipedia.org/wiki/Cottontail_rabbit Many subspecies can also be added to the rabbit. https://en.wikipedia.org/wiki/Eastern_cottontail There are many varieties of this animal. See if any kind of rabbit was not considered before.

I am working with Lopes on a document or series of documents about the fauna and flora of the maps (biome).   For now I am focusing on Copan in the highlands as a practical example.   In my research I have found 2 animal species that no one took into account in this discussion.  

The game lacks order and some coherence among its gameplay features. The problem of citizen soldiers who don't know when to be soldiers and when to be citizens. There are people who complain that sometimes when you're attacking you make a mistake and press the wrong button ( or you give wrong or DER with mouse pointer)and the soldier system starts collecting instead of attacking.

Someone took the time to talk about the project, about a different approach.   

Twenty years after its founding, 0 AD has been one of the most ambitious open source projects in the gaming world.   It's a game that competes with giants in its field.
