It's been said before, it will be said again.
Space is BIG. I don't just mean big, I mean REALLY REALLY BIG.
We are Tiddlers in an ocean.
It really is that simple.
Which is why Frontier will need to put a lot of thought into creating social situations.
Yes, theres events, which will help - if people can get to them - and if theres stuff attractive to people not that interesting in combat.
But there needs to be better general solutions too.
Things that create natural hubs, tools for emergent gameplay (like placing your own nav points), and a way for people to get back in sane time to the core systems if an event happens. (if it takes weeks of playing time to get back, the event will be over and people wont bother).
Not to mention better communication tools between friends, strangers and enemies. Ideally people shouldn't need to use offline/out of game tools in order to set meetings up.
