Not to divert the flow of discussion here . . . but . . .
Recently my players have asked what non-shift activities they could do while on a hyperion cruiser. I came up with a Rec room, Pilots lounge, Vid Room, Comm center, Exercise room, meeting with other pilots for some gambling, a chapel, and various groups that do 'fun' activies while off duty. Meet in rooms to roleplay, bible study, etc.
Any other ideas? I need more NPC interaction so they will care about the ship they serve on and the crew.
