I just started playing DD for the first time in about eight years today and completely loving it! I bought the anthology, so I've got all the games thus far, and various other goodies, but want to work my way through them in turn. I'd forgotten how complex the world of DD was, and how detailed. As the manual says, when you first start playing, you probably think hack and slash D2 clone, but as you go on you realise the complexity of the game world and the story you are working through. Well done, Larian Studios, and keep on working.
I'm also glad that the book that comes with the anthology explained where the one thing I didn't like about the game came from, the dreadful title.
