From the campaign:
Welcome to the Kickstarter for Thunderstone Quest, Alderac Entertainment Group's new version of the best-selling deckbuilding game designed by Mike Elliott!
You have two options to back this Kickstarter - the Adventurer Pledge or the Champion Pledge. The Adventurer Pledge is the standard game with everything you need to play including one Quest. The Champion Pledge contains everything in the Adventurer Pledge plus two more Quests, and a Premium Box.
All unlocked Stretch Goals are included in both Pledge Levels.
The Kickstarter campaign is more than 3x funded with still 30 days left to go.
