GalCiv2 has never been strong on documentation, and in a way that was fine as such, since there were not mega numbers of features to unwind. Usually when coming in at N00b level you could figure it out after a few games.
DA will be a different ball game, miners, spys, economic treaties, research treaties, combat system blah blah. Put it all together with the existing GalCiv stuff, and from a N00b viewpoint it will get confusing at the start, for some too confusing without uptodate documentation and an uptodate on-line manual on start screen that reflects latest changes.
DA is a "tipping point" on documentation, and although I am well, well, aware that documantation is never a favourite topics in developer circles as a genre, from a commercial perspective, it needs to be focused on from the time DA is released and on into the future. Without it there will be a significant number of confused bunnies out there who are new to the game.
GalCiv is starting to get near the 'mass appeal' arena, and to survive in that Commercial Space good documentation is a Commercial must.
