If I could put out a series of Rebellion Redux supplements that were geared towards me--a highly intrigued, relatively new, Traveller fan who will never own all the DGP stuff--I think something like a series of faction books would be great.
On the other hand, I like the idea of 'phase' books. So each book would cover a different phase of the war, as divided in Survival Margin. Each Phase book would give some detail on what life is like in each of the factions, how their rulers are doing (it would be a great way to chart Lucan's decline), and keep track of major and minor, but intriguing, events that the PC's could get mixed up in.
Just to be super crazy, each of these books could have a section devoted to how the war is affecting a given sector that is not necessarily part of one of the safes. Maybe they could provide a subsector or two of data, and some indication of how the major battles or economic impact of the war are affecting a locality. Kind of a slow motion Hard Times in some cases, although I'm sure some areas boomed during the first phases of the Rebellion. In others, I'm sure they encouraged some shaking up of the politcal landscape.
Anyways, I'd love a set of chronological source books or faction books, or both...
