Thanks everybody!
I took a few weeks to play around exploring in Heart and Soul Nebulae when I realized I was seeing a lot of Earth-likes out that way. More before Heart and Soul; less after. I got really curious why, but then I started imagining what it would be like to pop into a system no one's ever been to before only to have my ball light up with ships doing their thing. For some reason this made me think back to Firefly and Battlestar Galactica. I believe both Firefly and Battlestar Galactica took place in binary systems. I always thought this was stupid. If you have space flight to other who would willingly hang around? Best to leave before the totalitarians set you on a Mars with a space suit, hab the size of a small car, and an oxygen quota. But then I wondered just how many unicorns like a 12 Earth-like system would Elite have. Coolest thing though would be to pop into an undiscovered system, start snapping screenshots of all the insanity taking place, and then by the time anyone else gets there the whole community occupying it just... leave - migrating civilization. It'd be wolpertingers all over again!
