All that is in there now is the Campaign Ideas section, which I admit is very generic. And an into adventure in the back, which is very specific. This probably needs some guidance from Matt. I'm of two or three minds on this.
First, I'm not sure a 'Pioneer Universe' like the Third Imperium or 23300AD is the way to go for something so near future as to be obsolete (or parallel universe) by the time a book hits prints - and our friends over at SpaceX (and Rocket Labs, and whoever comes out of the sea of startups and actually gets something new and different to work) are not making that easier.
Second, what's the greater interest: sandbox (which is what we've built) or adventures (which are littler books) or campaigns (bigger books, sets of books, etc). As it is, we're looking at a First to Mars adventure book and an slightly later tech open-up-the-outer system sort of book (At least that's my thought - maybe then there's a fusion drive). I'm a sandbox sort of guy, and honestly every Traveller (or D&D, or Runequest, or a few others) campaign I've been in has been homebrew (LBB-based mostly to be truthful - though I did run a solo PoD that got me back focused on Traveller - so that's 3I).
Third mind is: if there is more focus on a specific setting, how fictionalized does it need to be to avoid throwing Elon Musk or a pile of trademark lawyers into the mix?
I'm also an old school Lego person: Give me a giant box of plastic and let me build stuff with it. Not doing those kits (okay, I have a few kits, but consistency is for wimps). So I guess I'm reflecting the question back: 'What do you want to do" - here's a pile of tools and parts. How much blueprint do you want or need? (Yes, I'm speaking as a creator, not someone who has to sell stuff to people - so like I said, Matt should probably weigh in) .
