On that note, I wonder if there was any thought to trying to harmonize (or at least reference) the different treatments of the Survey Index, now Universal Research Mechanic, across these products and the new World Builder's Handbook?Between The Great Rift, Deepnight Revelations, and this book
With Rim Expeditions and the World Builder's Handbook being released so close together I presume they were developed in parallel and there wasn't much time to compare how each would handle similar subjects. Although I note that WBH does make reference to the Great Rift set's Deep Space Exploration Handbook, and Rim Expeditions notes that it basically includes rules and mechanics previously published in that product.
I suppose the abstracted supply and maintenance rules from Deepnight aren't referenced in Rim Expeditions because the former has more of a focus on methods to move Travellers swiftly through very long interstellar transits, while Rim Expeditions is more focused on conventional campaigning and gameplay, but in a long-duration/distant region exploration setting?
Anyway, there's a lot of neat ideas and mechanics across all these books that can sort of work together and, taken together, have the makings of an intriguing toolkit for long-distance/long-duration exploration campaigns.
