The galaxy in Avorion currently seems to be extremely hostile. Most times I try to go into a quiet astroid field or salvage some wrecks (or just float around a sector for a while), a bunch of pirates or aliens jump in and try to turn me into shrapnel. And it's not just the aliens and space banditos, every faction seems to be constantly invading their neighbors. The first time I encountered a battle between NPC factions I stopped and watched the show (because the fights do look awesome), but after playing for a while I don't even pay attention to it anymore. There have been a number of times where a battle was raging between factions, and both pirates and aliens had spawned in and started shooting everyone.
My point is that hostile NPC spawns are, in my opinion, too frequent. I know pirates, aliens, and even headhunters surprising players can be an interesting and exciting event, but when it's common in faction space and guaranteed in unclaimed space, it's just annoying. I think there needs to be at least a few peaceful spots in the galaxy.
