Here's some more work on art styles. I did some side-by-side comparisons and I think we can consolidate all of the South American (Inca), Mesoamerican (Mayan) and Aztec styles under one style. I also looked at the Native American style, but it has close to 20 distinct units and because it is being used for two civilizations (Native American/Sioux and Iroquois), it gets a pass.
Between the three styles, there are only 8 units that are specific to one style. The South American style has a unique Axeman. The Mesoamerican style has a unique Crossbowman, Maceman, Musketman, and Spearman. The Aztec style has a unique Grenadier, Heavy Pikeman, and Swordsman. I think there are ways to repurpose some of these units.
The South American style's unique Axeman is named "Elite Quechua" (upper-left). It's only a flavor unit, though. It has no special abilities, unlike the Quechua. I think we should go with the Maya unit instead (upper-right). The Mayan special Maceman is not very interesting (lower-right). It looks a lot like the generic Maceman. The South American Maceman (lower-left) looks much more appropriate.
The Mayan Crossbowman (upper-right) and Spearman (lower-right) look much more fitting than the Incan units on the left. I think the Spearman looks especially more appropriate for the Ancient Era. This Spearman is kind of weird in that, unless it is an assimilated city conquered by the Mayans, a city will produce Holkans instead. So it would be extremely rare to see this unit. If we use it for Aztec and Inca as well, it becomes far more common to see.
The Aztec Heavy Pikeman is supposed to be an Eagle Knight. The other Heavy Pikeman next to it seems a better fit.
There are separate Incan and Mayan Musketmen; I like the Incan better. I noticed as well that there is no Infantry for any of these three civs and I will take a look to find one. There are some other holes in the unit rosters that I want to fill, but as it means repacking the FPK, I want to do that later.
Also, I think the Aztec Grenadier does not look very good; it looks too European and I would rather use the Incan Grenadier on the left.
Finally, we have the Swordsmen. The Aztecs have a "Jaguar2" Swordsman and the Incans have a Swordsman. I think we can use the Jaguar2 as a Swordsman for all 3 civilizations and use the Incan Swordsman as a Heavy Swordsman. None of these three styles has a Heavy Swordsman defined and thus they fall back on the standard (European) model. I would like to avoid this whenever possible.
