I got the game when it came out and beat it in around 3 weeks or so. Never went back to it. Unlike BB I never felt the need to revisit the game.
Ah well, your loss. Because how the game was at launch, and how it is now are very, very different things. An enormous amount of content was added and the whole structure of the game was drastically altered.
In the game as it stands now, you can't powerlevel yourself to the point where you can brute-force the encounters because of level caps and the inability to acquire higher-tier weapons and armor outside of each increasingly difficult story cycle.
This is the thing what makes the game so special. Its not just that they added a bunch of additional story areas and side missions, its all integrated into a much bigger game. What works on the initial story cycle simply no longer works on the later rounds, and unlike the rigidly one-way path of escalating difficulty between ng, ng+ etc. like you see in FROM's games in Nioh you can freely mix-and-match between mission on any difficulty you have unlocked to that point.
