In an interview published on the latest EDGE magazine (November 2018, issue 324), Narrative Director Mel MacCoubrey explained the research work into Ancient Greek literature that Ubisoft Quebec did for Assassin’s Creed Odyssey. She also said that the game won’t have the same ‘grimdark’ tone throughout it all as lots of triple-A games, mostly because of the funnier and more imaginative side quests (the main quest will be more serious and accurate to history).

We did a lot of research into Oedipus Rex, the Odyssey, crazy stuff like Lysistrata – all of these amazing Greek texts. We looked at which of them would be structurally sound for an open world, and how we could mix the structure of an ancient epic and a Greek tragedy into one, and that very much influenced who the protagonists then became – they’re brought from tragedy into this big world experience, and you see it all through their eyes for the first time.
