I get where you're coming from, and I think I agree.
Both in gameplay and story really. I think the story part is obvious, but the first time I got into a text adventure segment in Nier, or when the camera switched to fixed RE-mode or Isometric RPG mode was also pretty special.
Still hyped as fuck though.
Taro is well aware of that, judging from that S-E interview, he says they want to keep the different game styles theme, but they don't want to repeat the same ones, because that would get stale. Same for save deleting, they want to mess around with unique concepts regarding the endings, but not the same thing again.
