Congrats on finishing it, glad you enjoyed. It really is a mighty good game.
It's the third time I finish it, actually.
Fortunately it was along time since I played it last and I remembered very little of the details, so it was almost as fun exploring the Abyss this time as it was the first time.
I hope you enjoyed the sound!
Well, it didn't detract from the enjoyment, like the Soundblaster effects did. But even with Roland emulation, the sound is still rather weak compared to contemporary Amiga games, or Doom which was released a year later.
Doom had fantastic sound, while I think the sound is the weakest part of Ultima Underworld.
