Pilgrim's Progress

From the packaging:

Based firmly on Bunyan's classic tale, this computer adventure game by Anno Domini is designed for adults and young people from 13 years upwards.

You play the part of Pilgrim, meeting all the trials and temptations he finds on his epic journey to the Heavenly City. And you decide how to surmount the obstacles and deal with the dramatic problems he faces along the way.

You will frequently need to refer to a Bible for "clues" to the next move... so the game offers not only drama and thrills, but also extends your Scripture knowledge.

The entire "journey" will take the average player several weeks of occasional playing to complete, and offers up to 100 hours of excitement.
