The Crystal Chalice could best be described as an advanced adventure. I had no trouble with loading or with the well-written instructions.
The game starts with a title page and very good use if made of the Dragon's meagre sound facilities. The actual game, however, is less inspired.
There are text descriptions of each location, some filling up three quarters of the screen. You are told just a few of the commands available, and there are many others to discover as you try to find all the pieces of the legendary Chalice and place them back in the Palace.
The program responds fairly slowly and has a couple of game errors which do detract from the overall adventure.
For instance, if you type in SAVE to save the game for future play, a funny message about a bird appears. You cannot enter another command and the program eventually breaks with a "File Not Open" error.
To its credit, the adventure is quite large and definitely complex.
