While Horizon had better initial sales, as more people get Switch in their hands more people buy Zelda. But 2017 is dominated by Breath of the Wild so far this year from both a critical and sales standpoint.

And thats just the Switch version.And the Switch is supply constrained.

But the important thing here is that both great games got great sales!

Congratulations, Zelda! You proved all the naysayers wrong :)

Mario Odyssey is watching closely.

2 Switch games in the top 3! Nice!

It's also the best game of the year....

I guess the sales will get another boost the moment the 2nd dlc pack releases.

And when shortages will be resorbed.

Im going to be so annoyed when Mario Kart outsells it. Hopefully LT sales for BOTW pass 8

I know! This isn't even including Wii U or Digital on both platforms! It's probably well over 4.5 million at this point.
