I got mine in the Kickstarter. I've played Traveller since 1981 (38 years...) and I've loved ships, deckplans, and the advanced character creation, esp of various militaries. However, for a long time, there was nothing really usable as a way to run an active duty campaign. Now, for small ships like a Gazelle class close escort (about 3x as large as a Free Trader), you could probably ad-lib that one as a GM. But the books about major fleet elements had destroyers, cruisers, battleships, carriers.... nothing you could play with except as a wargame of sorts. You are pretty small on one of those 500,000 dTon battlewagons.
Then, along comes this Kickstarter and we get a 'big' ship compared to most of the ship's players will ever own. About the only close examples I can think of sizewise might be King Richard liner or the Azhanti High Lightning Class Cruisers. But none of those took the time to focus on the role playing aspect of "How do I play an active duty campaign on one of these?". That's where the magic in this product lives. It not only gives you the huge pile of cool deck blueprints and some description of what and where, but it deals with how you can actually have a role-playing campaign amidst such a vast vessel.
Now, from the KS, but not in this, we got the first adventure (and there are several others) that form a campaign which will give even more info on how to run a long campaign from a big ship. It's a kind of gaming many of us imagine we'd love to do, but never really had a good guide on how to do it and how to not simply make the players the senior officers and then watch them try to become bandits with the Dread Death Planet Roberts.
This product and the adventures that need this as a base are as good of a take on how to actually run an active service campaign as I've ever seen in any game that involved large military vessels or big units (grounside). The campaign style is different to your 6-vagabonds-in-a-40-year-old-tramp-trader. These people operate in a world of ranks, rules, laws, and orders. They also live in a world of tough fights and a lot of things that force can't solve directly (and some good practice at other means of dealing with situations). I think this is such a breath of fresh air for players old and new that most of us, finances allowing, should add this one to our collections.
I just wish I'd had the money to join the Great Rift kickstarter too. This one won my heart though. And my wallet, and I don't have as much to spend as I once did. I have a redhead in middle school that has first call on available monies. (Pity the mustering out benefit for some PCs isn't 'child support' or 'a dependent NPC').
