There seems to have been a glut of decent Strategy games in the last few weeks, could this be another one?

3DGamers has a single player demo of Nexus - the Jupiter Incident, formerly: Imperium Galactica III: Genesis. For a change, It's a quite reasonable 115mb download.

"Nexus - The Jupiter Incident" is a real-time mission-based tactical space game featuring spectacular real time battles and breathtaking motion picture quality. Focus on tactics and action as you control up to a dozen battleships encountering aliens, unknown solar systems and astrophysical phenomena in your struggle to save Earth.
