The Nintendo Switch comes with 32GB internal memory, but only roughly 28GB are available for you to use, this means that once you fill up that space with photos, save games, and game downloads you may need to invest into a SD card to extend the internal memory, the cost of this depends on the size you chose. Here is a list of games, and the size they will occupy on your Switch! It’s important to note that Dragon Quest Heroes can be purchased from the Nintendo E-Shop store, but will need a SD card, as the internal space will not cover the size of the game.

Mario Kart 8 Deluxe – 7 GB
The Legend of Zelda: Breath of the Wild – 13.4 GB
I Am Setsuna – 1.40 GB
Nobunaga’s Ambition – 5 GB
Puyo Puyo Tetris – 1.09 GB
