The Exodus Expansion of Battlestar Galactica adds some very nice elements to the overall game. In addition to getting additional character cards, this expansion also brings some nice ways to subtly change your gaming experience. There are additional cards for the destiny deck, the skill decks, and there is a new role card for a special position (the chief pilot or CAG). There are 3 different expansion scenarios to spice up the type of game that you are going to play. While you wouldn't want to throw them all together they really help to ramp up a game that you may be getting bored with. There are elements from this expansion that you can add into almost any game of Battlestar that you want to play. I highly recommend it but I would say to get the Pegasus Expansion first.
