"All civilizations use the four resources food, wood, stone and gold, but not all of them collect them in the same way, use them in the same way and need them in the same ratio.”
Gamestar Magazine,Adam Isgreen
Maybe it is similar to this:
Mongols gather his food from sheeps,cows etc.or mongols have a special bonus for gathering food from sheeps?
And englands have a bonus from farms?
Are you want this?
I think it is good idea for feel “horde”
