I was quite happy when they came out with "Return to Zork" That was a fun game, and they did a nice job with all of the images, voices, and the general feel, I thought.
One of my all time adventure type games will always be Bards Tale 1 and 2 (we ignore 3 in this house hold, it was just bad). Good puzzles, no railroading over plot, they were great games.
