You can't recruit multiple units on 1 AP (this was meant to encourage you to buy more expensive units, but I think I overdid it with the cost growth.)
And on the subject of cost, food costs are inconsequential and iron costs crippling. There's almost no need to try and get food, unless your army is almost entirely made up of the weakest units.
Incidentally, this makes the pikeman and such about four times as expensive as a swordsman...despite only being half again as strong.
I'm glad you asked about the "supply ship", it helps you traverse the deep water tiles, by being a cheap, disposable ship (you wouldn't want to lose a transport, would you?) I'm thinking of making supply ship be the exception, and allow recruiting more than 1 per turn, what do you guys think?
Yes, but what does the supply ship
do in the deep-water tiles?
