An incredible feat for 1971, and a product that has only been improved in the years since. I decided to get an emulator and try this original version out following the Gaming Historian's video, and the fact this was made by three people yet has had such an impact on edutainment and adventure games in general is worthy of praise. The only other game in this series I've played was the Fifth Edition that the library I used to live nearby had a copy of, so it was fascinating to see the similarities and differences compared to the sole exposure I've previously had.
