Cheers, seems like a nice place inhabited by jolly good sorts

Yeah, I figured there was some "upkeep by individual soldier" kinda thing going on. I'm spoiled by the later games' massive unit sizes because big armies are totally flashy, but IIRC they didn't affect the costs and such on the campaign map. I want that, but being "new" to the game means I'd rather have the flashy big armies affect the campaign too much. So I'm thinking I might want to have a go at modding the sizes/costs of the units so that I could have units the size of large/huge settings that are about as costly as the ones in default settings.

How hard would that be? Is there some general settings files I could play with, or would I have change the costs of every single troop type?
