add taxes, custom trade goods, selling specific items, custom weapon fits based on the economy, specific ships, engineers maybe?, powerplay related stuff...etc There is so much emergent content that could be created from this and who knows what frontier has in mind for the future that could be added to player driven content.
How would any of that work?
Taxes? How - what for? Where would the taxes go? Why would other players use your station if things are taxed?
Custom trade goods - How would FD determine who could create them? Favouritism accusations would be incoming? Or you create yourself? Assuming FD could give the tools, then how are prices set?
Selling specific items -eh?
Custom weapon fits based on economy - if FD did this, they could do it without player owned stations. If for player owned stations, then again, accuasations of favouritism if it was somehow limited to only player owned factions. At least if player owned factions can become powers later on with custom modules it would be earned, but otherwise at what point do FD allow this sort of stuff? What if its OP? Imagine the rage from others! What if its UP? Imagine the rage from those who own it, and their demands for a buff! And besides... usual issue, you want to limit it somehow? Perhaps only people can get into your station in Open? Or anyone can buy your specific weapon? Or you want only "guild" members to have access?
Engineers - for player owned stations? Hmm.... FD have to come up with engineers as well? What services can they offer? Again, anyone can access? Or limited? What are the crteria for getting an engineer?
Finally, what actually would be emergent about any of this? What player driven content would occur?
I'm not saying player owned stations are a bad idea specifically, but so far i've not seen really any good proposals that either are not simply weaksauce variations on what we already have, or require changing the game fundamentally in a way that would make ED no longer be the ED i bought. Basically you just threw a few keywords out without giving details of how such things would work and what the benefit would be.
Perhaps something best for another thread though, but its not like we haven't had such threads before (and we will have again).
