Back before I knew of RebED I played as the Rebels, Small Galaxy, medium difficulty. I liberated two of the systems in the Seswenna sector causing the loyalty of Coruscant to shift my way. I tried to go to Coruscant directly, but my fleet of Corvettes with an Escort Carrier was no match for a Star Destroyer and accompanying TIE Fighters. I had to withdraw, but I decided to blockade nearby Ghorman in hopes of luring the Star Destroyer away. It worked. As soon as I saw the Star Destroyer was en route for Ghorman, I booked it back Coruscant. After a long one sided skirmish with the unaided TIE Fighters, I had Coruscant blockaded, but I knew I didn't have much time before that Star Destroyer came back. I had Luke and Han and some Twilek and other pro alien sabetours en tow, so I managed to sabatoge the GenCore Shield (of course Luke had to be a decoy or else he would fail because the emperor). By now the Star Destroyer was a day out, but they still had a KDY Ion gun still functioning. I decided to hell with it and bombarded the planet once or twice. I had an admiral and luck on my side, and Coruscant for the first time in a long time declared neutrality. Luke confronted and captured the emperor as he tried to break through my blockade (with help from my fleet I am sure). I decided to jump out before the Star Destroyer arrived, and I guess my stylish good looks or good sense of timing appealed to the inhabitants of Coruscant, because they immediately joined my cause. That was day 125 and the crazy thing is this was actually standard game victory conditions. Don't ask me how I captured Vader before hand because I have no idea.
