No? Let's see...
The Homeworld is obliterated by a superiour enemy force. The last survivours flee in a massive ship. Most of the people in the ship are inside of stasis pods, but some are awake to crew the ship and it's attending escorts.
And now tell me wether I wrote about Blue Planet or Homeworld...
You wrote about both and neither at the same time.
-In Homeworld the cryo storage people aren't survivors, they're colonists. They don't even know there's a war going on until they've already won it and have been re-awoken.
-The Orion is not "massive" by any definition of the word in Freespace.
-In BP the humans lost their homeworld. In Homeworld they basically just lost an ancient colony.
-The survivors in BP don't flee, they hide. In homeworld they don't flee, they return. They don't run away, they head back home to their real homeworld. Return out of exile essentially.
The REAL difference is that the Orion in BP is essentially an Ark. It's a ship to keep humanity going after the Shivan's flood in and annihilate everything. It was never meant as an ark, it was simply retrofitted into one when the world went to hell. In Homeworld, the ship is purpose built to return home. It's self-sustaining, with the facilties to construct new fleets and technologies. The journey the ship takes in homeworld is one that it would have taken REGARDLESS of whether its world was destroyed or not.
Or in other words, the main theme is very different.
