I’ll toss out an idea, although I’m more interested in what others who’ve played it more have to say.
Bottom Line: Player ownership. The ability to “Own” a piece of “land” (space station), no matter how small, and the ability to improve upon it.
Imagine: for 5 million credits, you get a personal parking space in orbit around a planet, or out in the middle of nowhere orbiting a star. For another million or two, you can add automated defenses. You could add a navigational beacon for friends or for the public, so they could visit your ‘base’ (similar to dropping out at an USS).
Next up, add on some basic ore processing facilities, allowing you to extract higher %s of valuable metals out of raw ores than your shipboard refinery can produce. Might as well add a second parking space for your friends or partners to dock.
By this point your base is starting to produce a fair amount of heat, and might show up on non-friendly scanners as a USS. Better beef up those defenses. Or you could add an improved reactor or cooling vents to reduce your station’s heat signature.
How about laws – i.e. for the 100kms of space around your base, you set the rules (from a list of pre-defined options. Ban/Allow specific commodities (although you may still be subject to the laws of the system’s controlling faction - unless you become stronger!), add a no-fire boundary around your base, etc etc.)
The larger you get, the more you could start offering services. Perhaps you could serve as a way-station for turning in combat bonds, bounties, etc (i.e. by providing the service (to the faction/system), you earn a 2% commission on any payouts). How about fuel? Everybody needs fuel - and you could sell it. Munitions, repairs, etc… etc… Obviously you’re going to need raw materials and parts shipments… this will require loading bays, larger docks, etc etc. Perhaps you allow for a ‘free market’ on your station (i.e. NPC weapons manufacturers / ship manufacturers could sell their goods from your base) and simply take a small tax on each transaction?
Heck, you could even start leasing out ‘private docking bays’ and ‘luxury apartments’ for other players.
Of course, all of this requires increased power generation capabilities, core infrastructure and hull upgrades, improved defensive emplacements, perhaps the hiring of some security contractors… etc… etc…
I think I’ve made my point. And call me crazy, but given how many of these systems are already implemented in the game (from an NPC-only standpoint), I don’t think it would be too hard to make them available to players. Certainly it would take a few months of effort, but we’re not talking about major changes to the engine.
Or is this an altogether different game?
