While I do have some notes my overall goal was for this to be a collaborative effort between the group as a whole rather than we solely running anything like a GM. With that said these are the ideas I had that I felt sounded kinda cool, but nothing set in stone.

Wide open multi-factional universe, I wanted to have a religious cult fanatically assisting our main antagonist faction as both willing hosts and other methods of cooperation. Think unitologists/dead space vibes. Was thinking that slightly post-apoc inspired with humanity having once stretched the stars before a major event caused a fracturing of human society to the point that many holdings are now independent feudal states spanning anywhere from a single solar system up to 6 at most, many of these fractured factions creating a patchwork quilt of feudal states for the RP to take place in.

Also wanted to include a cyborg-based pseudo-science transhumanist isolationist faction, somehow. Maybe we'll antagonize them ourselves.

Also thought old imperial colony ark ships might be the holdouts for the prior galaxy spanning human empire, so like traveling ark ships of super militaristic gung-ho for the empire type jarheads running around.

No other sentient life forms except for the bug menace and it's progeny. Plenty of weapon variety, plasma, laser, ballistic, anti-matter, experimental shit, making sense isn't a prerequisite.
