I've seen a number of people say generator districts aren't worth building before mid-late game, if then. Why is that?
Because a farm produces 12 food at base, while a generator produces 8 energy. Then taking into account that the base price of food on the market is 1 energy, even with a 30% market fee you can make more energy producing food to sell than building generators.
The food edict is cheaper and it is often easier to grab food boosting techs than energy ones.
The galactic market values energy very low compared to food and minerals. I think this is the main problem beyond early game... a smart player doesnt make energy but trades for it.Mid to late game, almost everyone has overflowing energy that it makes inflation of Venezuela seem like a joke. You barely even get relations surplus if you gift thousands of energy. But I guess this is what makes galactic market *work*, as in very active...
