Origins was first AC game I played. 3 months after completing origins, which had bored me to death, I tried my hand at Odessey. The gameplay was exactly same. It felt like I was playing the same game again. Exact same mechanics and combat style. Uninstalled within half an hour.
Then I tried Unity and Syndicate, because people praise them so much. And I realised that Ubisoft has been remaking the same game over and over for more than a decade now. They just change the setting and rehash everything. The animations in Unity look exactly same as Odessey.
I had the same fear when I picked up Miles Morales, that it would feel the same as previous Spidey game. But they quickly introduced a few new mechanics which made the game feel ever so slightly different.
