Quests will be related to the lore and resonate with the main story, driving gameplay: "We don't want to have quests just to get this or that." They don;'t know if the [[Horadric Cube]] specifically will be in the game, but since players love it, they work on story side with game and item designers to bring gameplay aspects like the Cube in "organically." The D2 team never set out to make the Horadric Cube, it came about through the design process.
