And does attrition, or disease, play a part in the game?
In a word, yes. I have coded most of the attrition already, including supply attrition especially for besieging armies. Basically, if an army doesn't have supply sources it suffers attrition if it fails a forage check. The forage check depends on the current forage value in the province and the size of the army. Besieging armies have reduced foraging ability.
Armies can also have supply units in them. 1 Unit feeds 12 strength points. Armies are required to use their supplies first, even if they have friendly cities in the province with supply capability. The only exception are rebels. I figure that they can live off of the land better than anyone else. They get to save their supplies unless they fail a forage check first. And they get a second forage check before suffering attrition.
Sedentary and Migratory tribes have their own food sources, and won't suffer attrition unless their food sources have been damaged/stolen. I haven't designed that yet. But it should not be too hard. Sedentary and Migratory tribes will be susceptible to some measure of famine on a random basis just as cities will be. (Meaning, I haven't coded that yet, either. )
Now as for disease - the game should have something. But I haven't designed it yet. For example: the Antonine plague. A real thing with serious consequences. BUT...if it's just something like 50/50 then half the time you play that scenario it's easy and the other half of the time it sucks. That just isn't very satisfying. I plan to have something in between, depending on the scenario.
