I can't recommend Fantasy Flight Games' co-op card offerings enough. They allow 1-4 people to play against an encounter deck that acts as the opposition and generates the story of the quest/encounter.<p>-Lord of the Rings: They have the rights to the books, not the movies, which allows for a ton of creative writing and characters. Definitely the heaviest and most complex of the three, but allows for the most granularity in deck building. Has an enormous card pool.<p>-Arkham Horror: VERY story driven, cosmic horror theme that draws heavily from Lovecraft writing, but isn't afraid to blaze its own path. Feels very much like an RPG.<p>-Marvel Champions: Lighter weight than the other two, but an absolute blast to play. Very pick up and play with minimal story, feels like an action brawler. The newest of the three. Deck building is much less of a chore than with the others. You pick a super hero, they come with fifteen hero-specific cards, then pick an aspect (think color from Magic) and fill out the deck with only cards from that aspect.
