"Choice of Alexandria" is an interactive iPhone game developed by Choice of Games LLC. In this text-based game, you have the power to alter the course of history and save the ancient Library of Alexandria. The game is written by Kevin Gold, the author of "Choice of Robots," and is entirely text-based, containing 90,000 words without any graphics or sound effects.

Set in 245 BCE, you play as a heroic polymath librarian who has been invited to Alexandria to tutor prince Ptolemy IV. The real Ptolemy IV was misguided by his advisor Sosibius, leading to the downfall of the empire. However, with your guidance, you can change the outcome.

You have the opportunity to focus on scientific inventions, working alongside famous figures like Archimedes and Euclid. Discover the steam engine, germ theory of disease, or even robotic automata, all thousands of years ahead of schedule.

As you navigate through the game, you will face choices such as depleting the libraries of other cities to enrich your own, achieving popularity for your scientific inventions, and protecting the legacy of the empire. Your decisions will also impact the character development of Ptolemy IV, who can grow up hedonistic and selfish or wise and just.

The fate of the city of wonders lies in your hands. Will you be able to save the Great Library and invent the steam engine two thousand years early?
