I've heard that the last mission, in space against the Droid Control Ship, was the best mission ever made in both RS and BfN. Plus one of the bonus ship was the Sith Infiltrator. And the ground has MUCH more detail than RS. (ie trees, etc) There are much bigger and more impressive ships to protect, like XWA.
However, from the demo, if you're playing a ground vehicle, control is generally bad, and thrust keeps cutting out in both air and ground vehicles. It sometimes is actually painful.
Hopefully there is a patch, or it's just a demo flaw.
At last we will reveal ourselves to the Jedi.
At last we will have revenge.
