Dungeon Deck lets you build a night’s gaming encounters in minutes. They’re on Kickstarter looking for funding for some expansion packs.
From the campaign:
Dungeon Deck: Quests allows the generation of a random fantasy adventure scenario by just drawing a handful of random cards from each of several decks. While the core intent of their kickstarter is to reprint the expansions (adding more adventure possibilities) if it gets enough funding two entirely new decks will be made available. One is a Camp specific event deck, to deal with those nights when the sleep of the adventurer is interrupted. The other is a Character deck that allows quick generation of personality for NPCs (and even blander PCs).
