How do castles work for Native Americans?

[homefry]

They historically didn't have castles, so do they need castles to produce their best units?

[Monsieur Alphonse]

In the Americas campaign there are no castles. All units including the Spanish are trained in cities.

Also, as Apacheans, you don't really have a town either. Just a mass of teepee's huddled together. If your playing Chichimecs, Mayans, Aztec, etc, then you get cities with walls and stuff.

In the manual, it says that I can look up the building planner in the medieval folder.

I can't find it. Do you guys know where it is?

The planner is on the disk in a .pdf file.
