I have been working diligently to build my space station for my game. My inital thought was to build a space station with full facilities...banking, trade, repairs, refueling, bars(to get jobs, hear gossip, etc) and more...
But the more I think about it, banks should be independent so players would have to manage how many credits they carry with the looming threat of other palyer attacks, piracy, etc...
Then thoughts of this lead to having all separated:
Trade Ports(trades and bars here)
Political Offices/Ambassador facilities(offices and bars here)
Player Bases(and/or planetary ownership)
all extending SpaceStation for graphics rendering, etc.
This would cause players to move around and not be able to do everything in one place, promoting travel, exploration, piracy, teaming up for protection in numbers(alliances?), border crossing, dealing with other races, etc...
I havent explored all of the possibilities of planets/moons due to size, but...
they could have multiples of each of the above on their surface...but thats much later on.
