[@Dead Cruiser] I mostly want to see who joins and the characters.

I guess I have a few questions though. You mention everyone is a blank slate? so does that mean the CS will be as simple as appearance and personality? 

And you say we gain traits etc randomly so we sort of randomly get put in roles? so we might end up with...for example two healers and no tank? 

Also, and perhaps most importantly, you say you have a plot ready but it will mostly be down to the players. Does that mean it will, in effect, be a sandbox? and you'll throw random events etc at us and the settlement we make?
