Ghost of Tsushima was a gorgeous looking game with some really cool quirks. But... the initial charm soon wore off and I got bored after a few hours of the same repetitive tasks*. However, I had come straight from playing the base game of The Witcher 3 so the next thing was always going to be dull in comparison.
*I guess that's the trap most open world games fall into but something like HZD or Spider-Man at least managed to be quirky enough to maintain my interest. Assassin's Creed, on the other hand, did not.
