I've recently been preparing to play through the Metroid Series leading up to Metroid Dread. I started with the original NES game, but since then I've come to the understanding that this book is the actual starting point for the Metroid Storyline. And I must say, I wasn't disappointed! Learning more about Samus' character and the Chozo, the origin of the Metroids and the Space Pirates. It puts the whole game into a new perspective. Realizing Zebes isn't just the Pirate headquarters, it's where Samus' was raised. Mother Brain isn't just the Pirate Leader, it's the AI heart of the planet CREATED BY THE CHOZO??? I learned so much about the status quo of the first game from reading this, and I almost want to play it again once I finish book 2. Or perhaps play Metroid Zero Mission, which I've heard is a remake of the first game. Either way, I love this universe and story and can't wait till I'm caught up!
