I beg to differ Kitkun. This expansion certainly could use a little manual or FAQ. For example, how is anyone suppose to know that TEC got a new frigate - the Ogrov, or that any of the races got these new anti-structure ships for that matter. Or, how is anyone suppose to know there are now mines in the game and this is how they work, etc.
As for advertising, most of it online has been about the TEC exclusively, and the Entrenchment "Feature List" still shows the Subspace Inhibitor, which as far as I understand it is no longer included.
Sure the paper manual that shipped with the game is now woefully out of date, but a small PDF of what people can expect from Entrenchment if they buy it would be great.
While I do read every change log, it contains a LOT of information the casual player doesn't know what to do with.
Basically, I like the game, I'll download and pay for Entrenchment, but it would be nice to have a nice, up to date description of the major new changes. Hell, maybe it will get more people to buy it....
