Someone pleaded for Imperium Galactic War but I got some other suggestions for franchises Stardock might have a look at for possible acquisition.
Probably a longshot, but if I don't say it, it'll keep gnawing at me.
1) Imperium Galactica
This would make a great real-time counterpart for Galactic Civilizations.
(If you (Stardock) want to have a look, but can't find a copy, I've got an extra one plus a disc with all updates)
2) Fallen Haven
Turn-based game where you have to conquer regions of a map (of a distant world) and fortify them. A lot like the game 'Z' but a lot better looking.
