I would (still) like to see a series of books set in the alternate timeline of Empires Aflame.
For example, I'd be really keen to see an EA counterpart to First Succession War (and of Historical: Operation KLONDIKE, if you think about it), which featured the events surrounding Operation BLACK SHIELD.
Also, it would be great to see an EA-branded Era Report, Field Manual, and/or TRO set in alt-3095, with more information on "new" factions such as the Terran Supremacy and the Rim Federation, as well as how the alternate hybrid realms (the Confederated Suns and the Magistracy of Taurus) shape up.
Plus, a few EA Turning Point files looking at key moments in the alternate timeline - such as the battle for New Avalon in alt-3073 - would be welcome also.
