Nioh is a great agme, I think the level design is the weakest part of it though maybe next the visuals (the art held it up though). The world is good but the majority of levels are really forgettable with exceptions.

The boss battles are truly exceptional and the OST was great, combat was also excellent, so I agree with you on all those points! Good read. I did notice you didn't mention how much easier it is to co-op in that game vs souls, that should be pointed out for potential buyers imo.
