I played a convention game that started on a Imperial Fleet in the Solomani end of things. It started just shortly after word came in of the assassination. Each table (there were 3) were captains of different AHL class cruisers. Each PC was a senior officer with an assigned loyalty. And he knew who he thought on his crew had what loyalties.
It got going really when the Admiral on the BB came on to announce the fleets plans and loyalties, some commandos stormed the command center, and the CVA hit the BB with its meson gun. The BB went 'ouch', turned, and blew the CVA out of the water. Both were ruins. The Admiral and all command authority was dead.
Then the fun began.
I ran a Captain of one of the AHLs. I got my ship out of there. At least one other ship had the head of the combat air wing launch his fighter (after escaping an arrest), spin his fighter and dump a nuke right back down the accelerator.... (ow!).
It was incredibly fun as there was a status board showing things like shields/dampers/black globe status, fire control status, etc. I don't know how many times people launched fighters, brough up shields, etc. as paranoia moves. Some escorts even got uppity and got vaporized.
On my own ship, the engineers had some alternate factional loyalty. I ordered the Marine major to sort out a fight on one of the gun decks. He was young (14 ish?) and the Ref asked him (playing an NCP) how to deal with it? Should he 'suppress' the deck? The kid was confused, so the NPC took his own head and used grenades and heavy firepower. We took a few casualties. But later, when the jump drive was down, I used that unfortunate incident to good effect and threatened to send the Marine Lt. (Lt. Mansel) down to 'assist in repairs'. Amazingly, the jump drive which was going to be out for two days got fixed in 4 hours. And we got out of that madhouse in one piece.
That's the kind of fun you can have with the Rebellion! And that's just at the outset. Espionage, various detective and film noire elements, outright military conflict, tragedy, pathos, you name it. The Rebellion has it all.
Except, as Larsen points out, an ending.
