We just live on the platform and try to deal with all of the problems while expanding to try and get rich.  I'll be an engineer, but with pirates out there, we'll need warriors.  We'll also need business people, basic workers, etc.  Even cooks and bartenders would be needed.  There can be a few dozen NPCs as well, in case there are jobs that need to be filled.  You can fill out the world/your team with them if you want, but they'll just be background for us the interact with.
