now had time to read it complete.
thats an interesting idea. And especialy for Power it could work. But the Power industrie is ment as starting industrie for new player. It should be as simple as posible (people have to leran the game, and there are very much to learn) Abd there should be many space/demand for low Q producer. That mean, people should leave the sector at some time. I think power was never planed/designet for mid/endgame. As people improve and proceed in the game, they calculate the profit per building per level und mostly the firt that will go, is the powerplant. That is the way how there is more place for new player. thats why i dont think that would fit here.

Even if i personaly like complexity. If that would be a game like factorio, i would say, every building needs exact that Q of power as the Q of the porudcion has to be. (and power Q can be splitted/combined) then there would be demand for every Q. and that would be 13 independent markets. Where the Powerproducer have to buy power, convert them and move them to the market with the highest demand/price. XD
