The Hitchhiker's Guide to the Galaxy

The Good
This was the first game to be adapted from a license, and Steve M's wit was a perfect match for the source material. This game houses the most hallowed of all confounding puzzles, the Babel Fish! Its other achievement is it broke the rules of classic text adventures (such as lying to you which ways you could really go!)

The Bad
I was not amused about that lying part at first (it's one of the first things you encounter!) Also, the game was quite difficult. I believe this game prompted the ratings system for all Infocom games.

The Bottom Line
If you loved the book and love text adventures, this is a match made in heaven!
