I just reached the final cut scene of Nioh where the main story ends!
To me, the difficulty is OK and my biggest challenge is the lack of free time to play it. Free time to play video games is a luxury because not only I need to have free time, I also need to decide if I want to use it on playing video games, among lots of other hobbits, and learning, upgrading work skills. It was a struggle but I managed to finished it without feeling too guilty.
