I just wanted to say that even though I have never played Galactic Civilizations it looks like GalCiv2 has some serious potential. With that said the reason I am coming here and posting this is because I do have some concerns. I do feel strongly that multiplayer should be included in the game design from the ground up and working out of the box. If I may make another multiplayer suggestion aswell, GalCiv2 MUST have simultaneous turns and also a save function that works. As much as I enjoy learning with the single player elements the replay value for me comes with real people. With GalCiv2 looking so good and fans of the genre still waiting for a true Moo2 replacement, Stardock has a good opportunity here. I'm sure GalCiv2 will be a good game but, if it shipped with a solid stable multiplayer component it has the potential to be a great game, even a classic.
Best of wishes, Zargrim
