At E3 2016, Nintendo officially unveiled The Legend of Zelda: Breath of the Wild (we had seen earlier builds of the game before it had a name) with a breath-taking trailer that took us on a tour of the Great Plateau. YouTuber Sauraen was greatly inspired by this beautiful introduction to the game world and sees it as a chance to be a pivotal moment for the series, much like the release of Ocarina of Time.
With that in mind, they've recreated the E3 2016 trailer using Ocarina of Time's game engine. All of the footage was captured in-game (manipulating the camera to create new "cutscenes" for the trailer), and the music you hear was recorded directly from a modified copy of Ocarina of Time, not made from samples in some music software. You can watch the trailer above, and you can compare it to the original by clicking here.
