Yoko Taro is somewhat of a narrative genius in terms of crafting concepts together and creating strong well done storytelling that actively reflects the themes here of humanity and perspective. It's something I think Automata does better, but what's here is actually still excellent. It's terribly paced, the entirety of Ending B/C routes is awful to do, even with its new perspectives. But it's genuinely good, scenes like the text adventure in the silent woods details how fantastic Yoko Taro is as a writer.

The gameplay on the flip end, is mostly awful, and that's mostly due to the limitations the game's thematic messaging entails (the enemy designs are forced to be simple and get more complex much later to reflect the rebuilding of the shadows' own humanity) and also due to Yoko Taro being considerably awful as a game designer to make something engaging. There IS actually depth to NieR's mechanics, but the kinesthetics of every single hit you do is so criminally awful that the only reason I don't say it's the worst kinesthetics of a game ever is because Drakengard exists and he made that too. Combine bad game feel with a series of repetitive encounters, a pacing that overstays its welcome, and having to do the game at least halfway through three times and you get a disgusting experience. The saving grace to its combat is genuinely well designed boss fights, which do a great job of creating challenging bullet hell waves you have to have key understanding of spacing to get through unscathed.

It's worth suffering through, though. There's so much good here tied to its thematics and narrative storytelling that I don't regret playing it. It's just the activity of PLAYING it in general is so decrepit.
