Hi all
The game is going to the printers now (the Revised version), so you should see it soon (not sure of an exact release date though)
Chris covered most of the changes. Everyone thought Starship officer should be a core class, so we did that.
Once the Officer went to a core class, the Marine NCO and the Squadron Commander didn't make sense as PrCs, so I combined the Starship Officer and the Squadron Commander, and modified the Marine away from a sci-fi version of the Fighter into what amounts to a Core version of the Marine NCO.
I also added Civilian and Corporate ships of larger sizes (thanks for the suggestion TranceJeremy

) and brought the Cargo space of the larger vessels more in line with their size.
Basically, the revisions were minor, but allow people faster access to crew command abilities (while still remaining modular), and to better allow folks to play really *BIG* ships.
And don't forget there's Phil's Star Ace game on the way, which will use the Blood and Space combat rules (though it won't have the construction rules), so if you get both games, you'll have a really cool space combat system *and* a really cool setting.
I'm writing the Star Ace ships for Phil right now, and I can tell you this game looks fun and Christopher Shy's art looks *fabulous*.
