I got so frustrated with Ultima iV that I quit the Ultima Series after that. There was a huge cave at the end of Ultima iV. I arrived there well prepared and made it all the way to the center of the cave. Killed all monsters along the way and after a long (few hours?) battle I had to realize that I did not have a specific item that I needed. This meant leaving the cave (with all monsters respawning), getting that item, and doing the whole battle again (AFAIR you had to do it all in one go, as you could not save inside a cave). On that day I decided to quit the Ultima Series and never looked back. But I still own the original Ultima IV game package.
