Inca summary

So from the videos and articles I've seen so far here's what info we've learned (feel free to correct or add) with a tiny bit of speculation.

It will play more like an Age of Empires 2 civilization. Large fortifications and what appears to be a defensive play style. aoe.ms/age3de The odd thing about this statement, though, I'll get to later when going over buildings.

Home City: I haven't seen anywhere it say explicitly, but it's obviously Cuzco/Kuzco. Nothing yet on any Home city cards unfortunately. https://youtu.be/GtF7BfCzMlc?t=118

Units: So far we have the Chimu runner an equivalent to the coyote runner, which is supposed to be good against artillery and skirmishers. 65 Food and 35 wood. https://youtu.be/GtF7BfCzMlc?t=129

Bolas Warrior, a ranged aoe infantry with slowing effect to its projectile and the tooltip notes that it's good versus cavalry probably occupying the Eagle runner knight role. 80 food 40 coin https://youtu.be/GtF7BfCzMlc?t=129

Huaminca Spearman, no tooltip specifying any stats or cost that i've found yet. Probably almost a carbon copy of the trading post ones in-game.

Jungle bowmen, again no tooltips but they do get stealth from the looks of the UI when they're selected. I don't think they're going to be the equivalent to the Arrow knight that was good against artillery if they get Chimu runners. https://youtu.be/GtF7BfCzMlc?t=174

Macemen, probably their Skull Knight equivalent. https://youtu.be/GtF7BfCzMlc?t=153

They appear to also get some kind of heavier boat, it has a very Kon-tiki vibe to it, and even has a small hut on it. They probably will also get canoes. https://youtu.be/GtF7BfCzMlc?t=121 (in the river) https://youtu.be/GtF7BfCzMlc?t=317

Buildings:

This is the odd part. Inca are supposed to play like an AoE2 civ but right away their "house" looks like a Chinese village that supports more than the regular houses of AoE 2 and 3. They could be kanchas that might function similarly to longhouses or villages.

They get a Stronghold which can build almost any unit like a fort can, and is probably the middle ground between a fort and a Castle/Noble's Hut maybe akin to an Agra fort upgraded all the way to a Red fort. (Dehli gate only adds damage, not HP) Again, I think it was supposed to simulate a castle from AoE2 but it seems to function more like a AoE3 European fort.

They seem to get their own War hut (A U shaped building in most vid caps) dock and a market. There's also a curious narrow building with a courtyard that could function as some kind of research building (Maybe like an AoE2 university) but no screenshots of a fire pit yet. https://youtu.be/GtF7BfCzMlc?t=132 and https://youtu.be/GtF7BfCzMlc?t=123

There's a farm and plantation in this shot. https://youtu.be/GtF7BfCzMlc?t=317

On the lower right corner of this camera pan there appears to be an Incan building either partly destroyed/built or with an intentional hole in the walls. It looks more like an actual house rather than the walled little trio of huts that appear to be their actual population buildings https://images.app.goo.gl/tGdFt2JCuWKJpuDr6 or https://youtu.be/GtF7BfCzMlc?t=123

Techs: They'll have big buttons but so far I've only seen the Stronghold big button. No idea what it does. Looks pretty cool though.

They'll clearly get all the resources so they won't be like the Iroquois and Sioux who are receiving a change to their resources via fur trading. It's highly likely, that the Aymara will replace the Incas as a minor native ally. Although the Uru people would also be pretty cool as their artificial floating islands on Lake Titicaca could be the basis for some interesting water combat technologies (too bad their language is almost extinct, they mostly speak Aymara now anyway).
