First off, rating a gameplay trailer off of how many 'views' it has on youtube has many flaws.  

To begin with 'replays' count for views as well. Not to mention the 'Playstation' youtube chanell has more subs then the 'Nintendo' chanel, therefore more people would've been alerted to the trailer. 

Second off, no Nintendo fan (outside of Nintendo fans who have subsribed to Ninendo) would've expected Zelda gameplay to be shown off at the game awards. And when they did find out, it was most likely from a seperate news channell, (ign, machinima, polygon, kotaku etc). 

So unless one amassed the views (clicks) from all the different sources that posted the trailer videos, one can't tell how much attention the trailer truly received. 

Not to mention rating the quality and hype generted from a trailer off of its view count is unorthadox, and ineffecient to see how much hype it's collecting.  

Syting Journalists (good ones), fans, gamers etc. would be a better way to analyse how much hype a trailer has created. ( I still can't decide on which trailer did it's job the best).  

I honestly feel as though I've just been pulled into a clickbait forum.

He clearly stated in the OP it just beat it in terms of YouTube views. That's it.

And retweets or twitter activity as well? I think. #imnotontwitter

Well actually Uncharted 4 being longer is actually a disadvantage. I remember reading somewhere that people can usually watch a YouTube video for 3-4 before getting distracted and its 15 minutes long. I'm not certain if that affects the views but I think it does. Basically if the Uncharted 4 video was shorter it would have more views. 

Also look at that Like difference, very close in views but huge difference in likes. Almost 30,000 likes for Uncharted 4 and almost 5,000 likes for Zelda.

It's also the gameplay reveal no matter what you say. It's Nintendos fault for revealing it the way they did so blame them.

Considering how long the Zelda franchise has been around, and the multiple directions the series took, there are different opinions on what path the series should take. This has divided the fanbase and no matter what Nintnedo does the majority of the fanbase will never be happy. Its something that plagues most of Nintendos franchises and its why you don't usually see an extreme universal amount of hype for Nintendo games.
