CariElf: [chuckle] True enough (about surprise attacks). It would still be nice to simply have a "Declare War" option, though. While I don't really care to give an enemy advance notice of my intentions, I've found (in other empire-building games) that it's sometimes helpful to do so.
A prime example: I'm playing as a "good guy" and I have an alliance with Empire A. Empire A is currently at war--and getting crushed by--Empire B. I, being A's loyal ally, want to help them, but I don't currently have the necessary military assets available with which to directly threaten Empire B. However, declaring war will often still do the trick of causing B to divert some of their military my way, giving Empire A a chance to catch its breath and regroup.
And yes, I know that in GalCiv you can still help your allies by giving them ships, money, tech, and whatnot; but it would still be nice to have the option of making a formal declaration of war.
Bhazel: Round-about is right! But I tried it, and it worked for me as well. The Altarians were all too happy to accept my offer of smacking around the Yor.
