Fantasy Flight Games makes a number of Living Card Games, we will be doing demos of two of them:
Star Wars! If your interested in using the force to dispatch your opponent or joining the dark side to crush the rebel alliance this game might just be for you!
Netrunner! Take the side of a dystopian corporation or a hacker fighting for every resource they need to survive in this Cyberpunk future.
Both feature deck building like in Magic the Gathering or Pokemon, but removes the chase of seeking certain cards as expansions are put out with all the cards to that expansion in a single package.
