Looking at the back of the box, bottom left, I see three icon: Strategy First, Stardock and the Infogrames Armodillo. What part does Infogrames play in the distribution of the product? Just a guess, perhaps Infogrames is responsible for the boxed distribution while Stardock provides the online purchase and support for both.
Or, maybe the Armodillo lept off the copy of MoO3 and onto the GalCiv box as I purchased it.

Bad joke, I know...
Actually, I just answered my own question with a quick search of the net. It appears that Infogrames is responsible for distribution of GalCiv in North America, so I was partially right. See the bottom of this press release: http://www.pcvsconsole.com/news/news.php?nid=1708
SO, while Infogrames is not the publisher of GalCiv, they are partially responsible for getting the game to market (along with MoO3).
