CEMU (wii u emulator) can start the game (Zelda of course). Might be playable within a year.
As for Nioh, don't know, maybe cause I have been playing Dark Souls as well recently, for that reason? But for me, it really doesn't matter much. I will give it a go when I am done with Dark Souls and that will be years and then maybe I will have a different stance. Also, that's just my thing. Ignore it, I am weird.
EDIT: Also, even if copycat, doesn't mean it's bad. Even if I am not that interested in it, I would still rate it highly.
