Currently on display at the library of WPI is Save the Princess — The History of Storytelling in Video Games. The exhibit includes many classic pieces of software and hardware (most in box, not operation), including a working NES, that exhibits the evolution of narrative in electronic entertainment and the technology that supported these developments. The displayed software encompasses a variety of Apple II programs, such as Zork, Wizardry, Castle Wolfenstein, Ballblazer, Mind Mirror, and Adventureland.
