As a kid I remember playing an old MS-DOS game that was kind of similar to MoO but may have predated it. You were in command of a new government on a resource-rich planet called Harmony and you had to steer your society through a star cluster full of intrigue and war. There was more of an over-arching narrative than something like MoO or Civilization, but much of the gameplay was similar. It had a bit of a Dune vibe.

For the life of me I can't remember what this game was actually called. Does this ring a bell for anyone else? Would love to look it up again.
