I didn't play the first one. Though I started playing this last night on game pass knowing nothing about it.
It's intense, beautiful, intriguing and I'm looking forward to playing more.
The game itself is more of a story that you sometimes sword fight in. Exceptionally linear, which to me is a refreshing change from the abundance of open world titles available at the moment. The story is interesting, though I'm starting to think I should play through the first one first, there is a recap at the beginning so I feel I'm up to speed on what's happened. The combat is fun, and very cinematic, it feels like every interaction has been coded separately.
Overall it's a solid 8/10 if you are a fan of narrative story games it's worth a look, though as mentioned I'd be tempted to start at the beginning, there isn't much hand holding through the features which I imagine is explained more in the first game.
