happens in the same universe

Somehow, amazingly, I feel like this needs to be clarified. The creator decided to put in a secret ending to his previous series where the protagonist, who rides a dragon, somehow slips into an alternate reality where you inexplicably suddenly play a rhythm game against an eldritch monstrosity and then get shot out of the sky by a literal fighter jet. And that universe is where Nier takes place.

Yoko Taro is an insane man and I love it. I still won't play Drakengard, but that's just because it's not a great game.
