I've added the ability to play Caravan in the Capital Wasteland with 19 pre-existing Npcs, complete with Dialogue and Lip sync.
If you don't have a Caravan Deck, Speak to Gob in Megaton. "I'm Bored, is there anything to do to pass the time?" He will provide you with a Caravan Deck and Instructions on how to play.
