Pretty meaty supplement for the price! Most useful for Traveller T5, but the bulk of it is non-mechanical and therefore system agnostic. This supplement includes "history" of the Galaxiad era, including the impact on Charted Space of the Empress Wave (with straightforward rules you can apply to worlds in your setting to see how they are impacted during and after the wave), high level summaries of how various factions and pockets have evolved, tips for refereeing and adventuring in the wilderness areas between polities, a few notes and stats on the Black Fleets, and only then do we get to the meat of the supplement... The Republic of Regina gaming kit! This section gives you an overview of this smaller successor to the 3rd imperium and is focused around campaigning in and around the Republic. It has some fluff to tack onto character creation given the different setting, a guide to technology in the Republic (with a page of TL16-17 equipment), stats for four TL-16 spaceships that you'd find in the Republic (including a J4 scout and J4 packet, an updated Beowulf far trader, and a Kerjon-class Exploratory Trader with a hop drive), and then finishes up with six pages of library data—single paragraph blurbs defining key terms, major players, and important worlds you might encounter in the setting.

X-Boat is spectacular and a worthy successor to the old-school Journal of the Travellers' Aid Society. Great design and art, excellent and creative writing–all usuable by a referee, and an excellent application of the hard-to-understand Traveler 5 rules. This is an excellent value.
