(Theres different planets for different races, but they have the same general stuff)

Bar
By far the humans bar is the most lively, since humans are the only race that can't be poisoned by alcohol. Its impossible for humans to get a drink somewhere outside of their own bar, however, considering they all have different ones that are poisonous to other species.

Club
Once again, the human club is most lively. While humans are partying at their clubs, the other aliens usually rent the space for meetings.

Crew headquarters A, B, C, and D
By far the most active places. Crew members and pilots wait to be hired, and Captains are driving a hard bargain. You'd never see Lucy at any place other then A headquarters, though.

Leaders room
On the planet living spaces are just that, and not anything fancy. Everyone has the same bedroom, bathroom, and kitchen and thats it. The only different one is the Leaders room. They have a living room and a war room, the living room used for meetings and the war room for them, the general, and their right hand man only where they discuss missions.

H.C. meeting area.
Every planet has this, excepting the human planet. A courtroom-like building for the H.C. to meet and discuss new plans and what missions to send which race on.

Jail
We all know this. Theres one on every planet, but nothing is made to last. Every Sunday a ship comes to drop off all the Prisoners to a planet. The planet has its own civalization of the criminals, where they can live freely but never leave. No ship except the one that comes and goes on Sundays is allowed anywhere near the star system, and the ship is thoroughly checked before leaving said star system.
