The Legend of Zelda series has been one of the most popular game series of recent history and with the massive success of Breath of The Wild, a sequel was inevitable but the main reason a sequel to the Breath of The Wild was made because the developers had DLC ideas.
It had gotten to a point where they could manufacture a game out of the post-game DLC, and that’s exactly what they did. When speaking with Kotaku, Zelda producer Aonuma said.
It is incredible to see how much input the developers still had once the game was released in term of post-launch updates where it got to a point where they decide to create another game altogether out of it. One thing is pretty sure that if the sequel is anything like Breath of The Wild, then it will be a massive hit.
