Story and setting for the most part.
However, I also think that the most memorable games are those that manage to gel storytelling and gameplay together, where the story is told via the players interaction and actions. Think Shadow of the Colossus, Deus Ex, Knights of the Old Republic, Mass Effect, Bioshock Infinite or Half-Life 2. Stories told via setting and gameplay.
