Ghost Stories is in my mind the best co-op of its type. The challenge of the problems the ghost deck throws at you and myriad of responses available to the player with uncertain outcomes provide great opportunities to discuss strategy around the table. Sixty minutes is the perfect length in my mind for this kind of experience; just right for that surviving longer than we thought we would feeling. It's just complex enough for real tactical depth, but not too complicated so new players can quickly get involved with a simple rules explanation from experienced players (the way co-ops games should be learned in my mind). This game does have a problem with it's poorly written rulebook, but I had the benefit of learning from people who knew the game well.
