It appears that Dragon Quest Heroes I-II is the game that won’t leave space for the installation of other games.
Thanks to the update on Nintendo’s Japanese site we now know file sizes for digital downloads of various games. As you may remember, Nintendo Switch will offer 32GB of disc storage.

Mario Kart 8 Deluxe will take 7GB of that disc space. I Am Setsuna takes 1.40GB, Nobunaga’s Ambition: Sphere of Influence around 5GB, with 1.60GB required for Snipperclips and 1.09GB for Puyo Puyo Tetris.
The interesting thing is the fact that the site mentions 32GB for Dragon Quest Heroes I-II. Is this a mistake or the entirety of the full space will be needed, it’s currently unknown.
