As the title hints, I have no idea how to elegantly describe what I'm thinking of. Are there any games out there that involve:

Commanding a capital ship in space in tactical combat
Managing capital ship(s) strategically - plotting courses, supply issues, staging ground operations

The picture in my mind is more grand than I'm making it out to be, so I might have to file it under "Videogames to Make."

I shouldn't be posting at 3AM, should I?
