A lot of the units are generalized. A swordsman is a swordsman if he's a Japanese samurai or an English knight. Armor is worked into the ages, Stone age gets no bonuses to the ATK/DEF, Bronze gets +1 to each, Iron +2 to each, Steel +3 to each. So a Stone age spearman is 0/2, while a Steel age is 3/5.
The game is fantasy based (with my inherent Northern European background biases
). Some of the tech tree was cribbed directly from Civ 5.
As for the archer units, there is the slinger (no tech), archer (archery), short bowman (short bow), long bowman (long bow), and crossbowman (crossbow).
Anarchy is sitting out by itself mainly because it is the default government type. Tribalism follows anarchy mainly because it is not necessary to have writing, but by the time you want a monarchy or republic, there will be taxes and laws involved.
I could rename a lot of the techs away from what they directly give. Tribalism could be Oral Tradition. Something along those line.
A limitation (this of Word) is that I am using the org chart smart shape, and it won't do multi-linked boxes. Of course, I could just do it in something other than word and have all the links I want then
