By LUDWIG VON KOOPA - ...Why would you buy this, I don't know.
Today, Nintendo and KOEI TECMO GAMES have released Hyrule Warriors: Age of Calamity on the Nintendo Switch for $60, after it was first revealed just two and a half months ago. Based on the announcement trailer plus developer commentary, KoopaTV said it would be a “real prequel” that was “canon.” We expected it to focus on storyline as it focused on the vast lore of The Legend of Zelda: Breath of the Wild, pretty much at the expense of that game having a compelling story. This was based on The Legend of Zelda series producer Eiji Aonuma stating that the game takes place in the crucial 100-year period prior to the beginning of The Legend of Zelda: Breath of the Wild, and players will be able to experience the events of The Great Calamity for themselves, “first-hand.”
Without spoiling the game, I can say that Hyrule Warriors: Age of Calamity does not do what one's first impression of it would indicate it would do. Or, put another way, the events of The Legend of Zelda: Breath of the Wild don't spoil the events of Hyrule Warriors: Age of Calamity.
Anyway, note how Nintendo is marketing Hyrule Warriors: Age of Calamity in its launch trailer. If you don't note how, I will note that for you:
