Thank you Coot. The game is intended to be an MMO so I don't think there will be any sort of single player campaign aspect to the game.
I don't believe that this is correct. From what I had read in the NA forum, there had been intended at least to create a big open world, ala Elite Dangerous, eventually. The engine and arena play is the first stepping stone to that.
Of course, it may take years or never happen at all depending on how hard it is to do. But the devs have big dreams at least!
