Chimaera

Chimaera is a fun text adventure that accomplishes a feat that very few - if any - adventure games can claim: offers a coherent and complete adventure with infinite replayability.Think of treasure-hunting adventures like Zork or Colossal Cave that you can play again and again with random geography but consistently logical puzzles, and that's what Chimaera is.
How does Chimaera actually play? In the words of its designer, Chris Newall: "The object of the game is to amass as much treasure and other property as possible in the tent at your base camp - which you have to find at some stage. There is no easily calculable maximum score but a scores of more than 1,000 should be achievable.
