Would there be a Quest Module to formulate multi-layered missions/quests based on random elements of the current condition to make things more alive?
Well, that's kind of the nitty-gritty of the trade system; depending on what the player wants to do, they can:
1. Trade for a profit, taking advantage of the market opportunities opened up by good / bad events.
2. Trade in black-market goods, undermining their relationship with a Faction but increasing their profit margins per run. I really would like to see that mechanically fleshed-out personally; instead of being an automatic debit, have a chance to get caught, pay bribes, have to fight your way free of a starport if you've been doing something really awful, etc.
3. Do something helpful about the violent activities that may be underpinning market instability, whether that means escort missions <shudder> or intercepting pirates or accepting something like a Letter of Marque (totally want to do that).
4. Do something harmful to the Faction's traffic, and then take advantage of the disruption to make a killing in side-markets that are also affected whilst also gaining some joy from piracy (or acting under a Letter of Marque, heh).
That's a fair amount of layered, event-driven opportunities to use real agency to interact with the game world; the problem's going to be presenting it in a good fashion, UI-wise, and making it relevant to the flow of play.
