I am in definately As for your questions here are my views
1. Aliens, yes or no? I think there should definately be aliens as for what types i think they should be somewhat regulated and if there where i think they should obviously not be the friendliess (i think i would like to see it as warhammer esque with most of the aliens being enemies of each other and of the humans but with some limited co-operation between them depending on the race
2. What is the political situation? Stable and peaceful with one government? A number of warring factions? Government against rebels? Post interstella war? I think a single government would do good but it would be at constant war with various alien factions and have to deal with internal problems which would make piracy a much more realistic occupation as hey the government is busy as shit our homes are ravaged by war why the hell not get onboard a ship and fly around doing piratical things better than sitting around and being drawn into the wars.
3. What sort of ship are we using? A modified trader vessel? A weapon less cargo friegther? A stolen battle cruiser we can't quite operate? i say we should be a military vessel whom mutined against their capatain it would ass extra stress fromt he government to hunt us down and give us a solid backstory and a reason as to why we have all these skills.
Also be thinking about the crew position you might go for.
as for what position i am thinking of either a officer/captain position or a position as a gunner.
