Modders are like modern-day magicians. They can combine two separate games and create one ostensibly cohesive world, even if it's for a small sliver of gameplay or (more likely) a short YouTube clip. Modder BigSharkZ combined The Legend of Zelda: The Wind Waker with a portion of The Legend of Zelda: Ocarina of Time, to wonderful effect.
“While it is not a full or brand new game, all that was showcased here will someday be made available in the form of a mod pack. This video was made in two weeks with very little sleep, as a proof of concept to show some of what can be done with Wind Waker modding.”
"However, please understand that this is a very large amount of work for a single person (over a hundred hours were spent working on this, for example) and that my free time is often limited, so it will take a while to have a proper release, especially when I have many other projects in the works," the modder added.
Fans have been experimenting with the Zelda-verse for years now. In the most recent example of visual toying-about, YouTube Channel Digital Dreams launched a video of The Legend of Zelda: Breath of the Wild in magnificent 8K. The video showed the most minute attention to shadows, glimmering of dust mid-air, and other effects.
