I am sorry, but I cannot agree with any of the positive comments in this thread for one simple reason: the product has no effective manual or documentation, and that isn't even MENTIONED in the change list.
Lest you believe I am here to trash Stardock, I will point out that I have been buying your games since GalCiv on OS/2. I installed OS/2 to play the darn thing.
The game is completely unplayable without any sort of end user documentation. The manual does not include simple basics such as how to zoom in or out. If you are not a veteran 4x player, you wouldn't know what the conventions are.
There is no documentation on multiple UI mechanical issues.
A software engineering company like Stardock ought to know the simple rule of software development: it isn't done if it isn't documented.
I know documentation is neither sexy nor fun, and that it is extremely tedious to do, and is expensive, and requires talented technical writers who don't add a single feature or fix a single bug.
AND I DON'T CARE.
If I cannot figure out how to play the game, the game is just a giant bug.
This situation is completely unacceptable, and whomever made the decision to release without a real manual (a PDF, or even a text file would have sufficed) should be ashamed of themselves.
I had enough faith in Stardock to pre-order, and now I am very, very disappointed.
EDIT: I should add that I HAVE read the woefully inadequate and unacceptable PDF that was included. However, it only has high level background fluff and high level game play concepts. No details at all, and no UI mechanics instruction. See my threads in the tech. support forum for details.
