There's a diffrence.

Lightning and the rest of the gang see on a new report that there is going to be a trail and then excution of Sazh and Vanille, and the leader of the the government will preside over it in person. Despite knowing it's an obvious trap, they all decide to crash the party as not only a rescue but a way to take down the controlling government a bit. The party is still Lightning, Fang, and Hope, so it's pretty solid, and Snow is floating somewhere off screen between cut scenes. I would think that a curent gen console could handle a party of 4...

Meanwhile Sazh and Vanille are locked up, with Sazh being quite alive. Turns out that he couldn't bring himself to shoot himself and shot the wall behind him, then the head of the military group made fun of him for a while and knocked him out. They make their escape when guards come to move them due to the chaos Lightning's group is causing, and Sazh's bably chocobo flies at their eyes. So now both groups are trying to catch up with each other as the situation goes to "CODE PURPLE!"
