As for "real trade and economy" I guess that depends on how you define it. I'm guessing that what you want (EVE?) will never be part of ED.
Well i think for the real and complex economy it's already too late.
No I talk about a system where npc still produce and consome. Buy where they really do they (actually a production npc don't need ressources they "magicly" produce it)
I want a system where a HUGE coalition of players can up or low a price.
Imagine for X station, There is Y tons of slave consume per hour and this production give food.
This "consumation" is actually "rp" maintain by npc.
If a lot of players, intercept (private open solo) a lot of npc convoy, by a % the amount of slave sold to the station Will be not enought, the station Will starve of slave and have a low prod.
This can upgrade slave price, security and pirates (more pirate npc due to the lot of agression, why not!).
And this station Will export less food to the next system and the next will starve too ect.
This system can simply give Life to the univers, give HUGE possibility to miners, traders, Bounty hunters and ofc pirates.
Cause If price can ne hight the same on the other side.
A pirate station with a lot of good stolen Will have a low buy price. And the smugglers are here for buy low price and help the station.
It's not Well explain here but you get it I think.
It's not the eve Way, it's a living univers Way, where trading isn't Just a bot activity, smugglers are usefull and the univers is Alive.
And that Just by consumation against production and trade between station-planet-system. And a % of loss dur to players/npc pirates.
Because actually a station can have 0 of minerals and have industrial activity.
They "generate" from nowhere and destroy ress When you sold.
