- Unit line upgrades decrease the cost of that unit by 10%
So for instance, Militia cost the normal 60 food and 20 gold, but Men-at-Arms cost 54 food and 18 gold, Long Swordsmen cost 48 food and 16 gold, and Two-Handed Swordsmen cost 42 food and 14 gold. The civ would not have Supplies or Champion for balance reasons.
Knights would cost 60 food, 75 gold, but then Cavaliers would cost 54 food and 67 gold (rounded down), and then Paladins would cost 48 food and 60 gold (rounded down).
Archers cost 25 wood and 45 gold normally, but Crossbowmen would cost 22 wood and 40 gold, rounded down, and Arbalesters would cost 20 wood and 36 gold.
All these discounts are added up from the base cost, but for balance reasons, perhaps the next discount can be 10% off the previous price.
If that were the case, Long Swordsmen would be 48 food, 16 gold, Two-Handed Swordsmen would be 43 food, 14 gold, and Champions would be 38 food, 12 gold. Perhaps Champions should be left off this version as well. Supplies is obviously not needed.
Paladins would cost 48 food, 60 gold. Perhaps they should be missing too.
Arbalesters would cost 19 wood, 36 gold.
Perhaps if we go with the second version, it should only be 5% off the previous price. Here’s what those numbers would look like (all rounded down):
Man-at-Arms: 57 food, 19 gold
Long Swordsman: 54 food, 18 gold
Two-Handed Swordsman: 51 food, 17 gold
Champion: 48 food, 16 gold
Cavalier: 57 food, 71 gold
Paladin: 54 food, 67 gold
Crossbowman: 23 wood, 42 gold
Arbalester: 21 wood, 39 gold
Here are some other unit prices as well:

Siege Onager: 144 wood, 121 gold
Capped Ram: 152 wood, 71 gold
Siege Ram: 144 wood, 67 gold
Light Cavalry: 76 food
Hussar: 72 food

Elite Skirmisher: 23 food, 33 wood

And so on.
