I have bought the limited edition of GalCiv2 from amazon.co.uk and every thing is fine. I obtained the SN as indicated, installed stardock central and updated. I think however that stardock central does not detect the collectors edition (am I right ?). I procceded to download and installed the CE enabler and the bonus pack - on top of the stardock central updates.
Now, my question is simply: how do I know that the game I am playing is updated with the CE content and the bonus pack ?? I don't think I see any mention whatsoever inside the game...nor when I launch again the stardock central...
By the way, although I bought the european version and my country settings are not English (Us) I have not (yet) found any graphical glitch.
