Finally took the plunge on Nioh 2 when I was stuck at home sick a few weeks ago. Well, Nioh 2 is more like Nioh 1.5, but I'm not mad. Still a pretty awesome game.
I just don't know how much time this one will drain out of me. I played well over 500 hours of the first one, and now I have even less time than I did back then. It sounds like this one is easier overall, so maybe that'll be less time spent? Hopefully.
The sense of progressing your character build in the first one was unbeatable, and I think that's where most of the series' appeal lies for me. It reminds me a lot of the Souls games, in that NG+ is harder each time (up to NG+4), but there's just more to it than that. Finding progressively rarer gear with more and better perks is pretty addictive, especially when you can level it up and reforge new perks on it. Just a whole lot of options you can choose from to become stronger, and it's really fun once you fully grasp everything.
