Philosopher’s Quest is a single player text adventure.
The story starts with the player mooching around a junk shop. Somewhere in the back of the shop is an old wand. Its just lying there and, well, what harm could come from giving it a little wave - especially if the shop keeper's back is turned. So that's what happens, the wand gets waved and the player is transported to another shop somewhere inside a cave system. Though alone in the cave the player hears a voice telling them to go and explore, to seek treasure and bring it back to the shop in payment for misuse of the wand.
So begins the adventure that will see the player encounter the serpent in the Garden of Eden, the Ancient Mariner, an invalid old lady, a whale and many other strange characters and places.
