Well, that’s a bit unexpected. While we thought that the official Zelda: Breath of the Wild game guide would be popular, we didn’t think it would be this popular: it’s the number 1 best selling book on Amazon.

That’s on Amazon, the biggest book seller in the world with millions of titles, and the best selling one is the Breath of the Wild game guide.

And it’s not even out yet. It’s just pre-orders.

With this sort of popularity, it’s bound to sell out soon. If you want a copy, get yours here.

Update: after the publication of this article, the book dropped to second place. It’s still wildly impressive that a game guide held the number one spot on the best seller list — as far as we can tell, it’s the first game guide to ever reach the #1 spot. (you can find the up to date Amazon best seller book rankings here.)

The 368-page Breath of the Wild game guide retails for $39.99 and will be out on March 3rd. The publisher also has a few other options, which will be made available closer to launch.
