AdventP

A game with similarities to the original ADVENT (or Colossal Cave if you prefer) but with many differences and an all-round tougher experience.

The game was written in CDC Pascal by George Richmond, with some help from Mike Preston. The original program, ran on a CDC NOS mainframe system. Jason Dyer aptly described it as being written "...like — the author played Adventure, liked it, had some notes — then decided to write his own game from scratch, riffing off his notes but filling in the gaps with his own imagination."
