There should be a community driven event where players can donate isk, complete missions and events (like hauling components) to build grand market hub stations.
The event would be something like -
”The empires have come together to recognize capsuleer market destinations as true market hubs. To fund grand building projects the empires have created Isk donation and mission projects. These projects determine the scale and grandness of the new market hub stations.”
The more isk and projects that are completed, means the size of the market hub station (and complexity) increases.
It could be a week long project (or longer) with special rewards as well as the top 100 could get their names placed on the station.
The station would have tiers, each increasing greatly and increasing the ‘perks’ of the trade stations.
These stations would be one of a kind architecture for each empire and there should be counter play for the event.
Tier 1 would be lets say 1 Trillion isk and 20 billion m3 of materials delivered. This would be a basic ‘trade’ themed structure with a couple undock points.
Tier 2 would be lets say 2 Trillion isk and 40 billion m3 of materials delivered. This would be the basic station with 4 undock points, additional decor like advertising and the top contributor would have their name on the structure with a plaque recognizing their contribution.
Tier 3 could be 3 Trillion isk, 60 billion m3 of materials. This would be built on the previous and would have 6 undock points, the decor, ‘Concord patrol’ windows where extra concord ships are on station to respond and they will respond with remote armor repairs to the victim ship.
you get the idea.
The goal - An isk sink that allows players to alter the game world. It should also have counter play options that rob the materials, or could use the faction warfare mechanic that the pirate nations ask to destroy ships hauling materials for the empire factions for the project. If the project succeeds the meta game of ganking and camping in those market central hubs change greatly.
The event could also start with Caldari transforming Jita to a major hub station. Then the Amarr empire, not wanting to be outclassed start their own project a short time after. The rewards could be limited time skins for that faction, mostly for trade ships, but combat ships as well (since haulers will need escorted).
