Must say, apart from the changes in the background fluff ( Human forces all becoming one, and under a very unsettling governance; The Relthoza and Aquan racial changes etc.) and from what we hear the rules changes in game play ( Hex-based fire arcs, for instance ), the FSA reboot seems to more resemble what Spartan coudl have done themselves to streamline the game and make it more interesting. Even the design style of most of the ships seems to maintain the original style of Spartan, with a couple of notable exceptions.
And I will therefore ask; Why was that not done with Dystopian Wars? Well, I know why and I can say it in three letters - W, W, and X.
But, personal obsessions aside, this does look promising for the re-release of FSA; For most spaceship gamers the fluff has always been optional, it's always about the ships and the gameplay foremost, so it's not going to be much of a concern about how the background works TBH.
