Assassin's Creed: Odyssey is an action/adventure RPG set in ancient Greece. The game is set in an open world in ancient Greece during a fictional version of the Peleponnesian War. Players have the option to choose between a male and female protagonist; the unselected character becomes the main antagonist. You start the game as a mercenary and grandson of the Spartan king Leonidas I and inherit his broken spear, which has been forged into a weapon with special abilities. Within the framework of the main story, the player tries to uncover the secrets of his or her origins and uncovers various conspiracies in the underground of the Greek world. The game takes place in real historical locations and integrates historical personalities, e.g. Socrates, Pericles, Hippocrates. There are numerous side missions and places to explore that are off the main mission. You often have the choice between open conflict or acting unnoticed in stealth mode. Assassin's Creed: Odyssey also integrates the Discovery Mode, which has been classified as educational software in Germany. All violent game scenes and mechanics have been removed, allowing players of all ages to view the ancient Greek world as a virtual museum and learn about the culture, politics, economy, religion and everyday life in Greece and Sparta through pre-programmed tours.

Our research on Assassin's Creed: Odyssey focuses exclusively on Discovery Mode. In randomised experiments, we measure whether players learn and remember information differently depending on whether they are taught text-based or through a Discovery Tour. For this purpose, we have developed standardised tests that measure the knowledge learned. For comparison purposes, texts with the same content were created for the different topics of the tours in the game, each of which is tested and evaluated with quiz questions. In relation to the Cognitive Theory of Multimedia Learning Theory, we are investigating learning on the visual and auditory channel.
