Not really, a lot of people (including myself) enjoyed the earlier games because they had some historical accuracy, both with the educational guide (discovery tour) section (which was really good in for example Odyssey) that goes over a lot of historical data, but also from how the games were constructed from the ground up. I'd say that the strive for historical accuracy has been one of the most important staples for the games series and one of the things that has separated them from others of the same genre.
"Maxime Durand (production coordinator/historical researcher at Ubisoft) "Our goal is to create a believable world that feels authentic, even if it’s not 100% accurate. We want players to feel like they’re stepping into history, but we also need to make it fun and engaging."
Ashraf Ismail (creative director of Assassin's Creed: Origins)"Our goal is to create a believable world that players can immerse themselves in. Historical accuracy is a foundation, but we also want to tell a story that resonates emotionally and is fun to play."
Patrice Désilets (Original creative director) "Our ambition was to create a game where you could experience history firsthand—not just read about it, but truly feel like you're part of it."
