Right ... yet even with food, there's a bit of a simplification in this game ...

Every single unit needs 10 to 20 food; it will be the same for all units in a given turn, and depends on your techs. It does not change if some units are depleted.

But the speed of replenishment depends on your overall kingdom food level, from Famine (-50%) to Abundance (+30%).

Anyway... it's all good. Just ... different.

Take care, thanks again.
