Same as Khamul & Endless, honestly. DD was an utterly unique gaming experience and really showed that the Larians have a different approach to gaming than most of the mainstream companies. Most RPG games (Of whatever type) seem to be designed to either compete with Diablo or to compete with Baldur's Gate, without any true understanding of what makes a great game. Some of them are GOOD copies, sure, but ultimately they're copies.
DD tried to do something a bit different. I have every confidence that D2 will, as well.
