mm, I think eventually the playerbase for this PG would be diverse enough that a home system wouldn't work for a majority of them. But, if someone can find a good independent AND uncontrolled system, then that'd probably be best. I use HIP 115247 as my home system. The only station there has a good shipyard and outfitting and missions, and the station is sitting between a planet and the planet's rings, with plenty of res sites ranging from low to hazardous. And then there's another ring planet 38ls (or so) away with more res sites since the two ringed planets orbit each other.
Wonderful little system and I love it. However it is Empire aligned, though uncontrolled.
