This is a fairly simple game. It starts with a person posting a random quote from any of the Star Wars films (obviously the ones that have been released!) and then people are to guess which character said it. Once the person posting the quote confirms the right answer, the person who game it gets to post the next quote.
Person 1: "No, I am your father."
Person 2: Darth Vader.
Person 1: That's right!
Person 2: *posts new quote*
If for some reason no one has guessed correctly or the person who posted the quote has not confirmed who was correct in a week, anyone is free to start over with a new quote so that the game doesn't die out completely.
And just to make it a bit more fun, don't google the answer.
