You know what I would like to see in Final Fantasy XVI? A real-time ecosystem in Final Fantasy XVI. Not just for money, but where organism affects the agriculture.
So in one sense, bugs (that are also enemies) could destroy crops that both beast and NPCs need for survival. If you need more exp, you could manage the bugs to get a certain amount of enemy in the area. You’d literally farm enemies in this sense.
Stock markets may crash, lowering your amount of Gil. One day a shop may have a discount when the economy is good. The prices might skyrocket when the economy is bad. This might give rise to underground markets, maybe even more crime and more enemies to fight in towns.
The themes in Final Fantasy XVI could be consequences to interconnectedness, to combat the divide we’ve seen in our world.
