Assassins Creed Origins.
The only thing I could really pin down that they do thats unique is an open world that you are only supposed to see each area once. If you play the game as intended, you move from area to area following the main story, and doing a few side quests in each little area along the way. It feels like this epic road trip through ancient egypt, and I LOVED that you never feel overwhelmed by the size of it, as each area is very digestible, only has a few side quests, and the stories are good enough that you actually want to do them.
I feel like some games have smaller open world maps that you see one at a time, but this one just feels different because its all connected in one massive map. So its not new really, but the execution for me was really great.
I'm halfway through Odyssey and its still really good, although I feel the overall world design has lost some of that road trip feel, I am playing it in the same way in that I will never go back anywhere unless I feel theres a story reason to.
