PDF Page 11, The Jihad:
The second paragraph of this section refers to the Jihad as "the current universe-shaking storyline". As of 2013, this is no longer the case; after a year spent exploring the fall of the first Star League, we have now begun to make the jump to 3145. Perhaps referring to the Jihad as a recently-completed storyline might better reflect the state of play, if there is no room to add an explicit reference to the "current" Dark Age instead.
PDF Page 12, Eras:
The Star League Era only lists 2570, the cusp of the League's foundation. Given the late-League works which have been covered as part of the "Year of the Star League", either 2750 or 2765 should also be added, to help bookmark the seminal events of that era.
PDF Page 12, Eras:
The Jihad Era is listed as (3067, CURRENT), the latter of which is no longer the case. Perhaps referring to another year of the Jihad/WoR era (such as 3075, when the Jihad was at its peak and the Wars of Reaving came to an end) might be worth adding as a second date of note for that era.
PDF Page 12, Eras:
The Dark Age is currently listed as (3132+), based on Gray Monday but skipping over the intervening Republic Era. Perhaps the years 3085 (the year of the early Republic Era's field manual and TRO) and 3145 (the point at which events are being poised in most of the current wave of Dark Age releases) might be worth adding. In addition, since we are now officially "into" the Dark Age from a CGL product release point of view, perhaps it (rather than the Jihad) should be noted as "CURRENT"... unless it would be best to leave the choice of present era blank in light of the upcoming ilClan/potential jump to 3250.
PDF page 24, Hanseatic League data point:
The current number of inhabited worlds listed for the Hanseatic League is "24 (est)". According to the maps of the League in Field Report: Periphery and Objectives: Periphery, the Hansa has 29 systems within its territory (at least as of 3079). In addition, the capital city is referred to as "Commerce, Bremen", while that planet's entry in O:P refers to the capital as Freie Hansestadt. (Unless the latter is meant to only be the planetary capital, and the former is a separate city hosting the governing apparatus for the Council of Merchants instead.)
-----
Just on a general note, I think it might be worth re-considering what era Total Warfare considers to be "current". If it is a good idea to stay in the Jihad era in terms of presentation, fair enough; but with the jump to the Dark Age, perhaps 3085 or 3145 might be worth highlighting, of not switching to directly.
(Which may or may not have an impact on which map is included, or whether or not the Republic of the Sphere is offered as a faction in TW itself.)
When the first edition was being published, it may have seemed that the Jihad sourcebooks would run for quite some time yet; but that time has passed, and a new era is upon us... for as long as it takes to make the supposed jump forward, should that come to pass.
