The Legend of Zelda: Tears of the Kingdom has been in development for many years now, and it's expected to be a rather big game. If you have been wondering just how massive Link's new adventure is, Nintendo's webpage listing suggests it will be a whopping 18.2GB in file size.
As highlighted by fans online, this supposedly makes it the biggest first-party title on the Nintendo Switch (and note: we're not counting updates or anything like that here, just the base game in its release state).
If the page listing is accurate, that would make it roughly 4GB bigger than The Legend of Zelda: Breath of the Wild, coming in at 14.4GB. Breath of the Wild also happened to be a previous record holder of this title. One other sizable first-party offering released more recently on the Switch was Xenoblade Chronicles 3, taking up 14GB.
Tears of the Kingdom will also cost an extra $10, with the game priced at $69.99 USD. Nintendo has publicly stated it does not plan to make this a trend, and decides pricing on a "case-by-case basis" - the file size may have played a part in this decision.
