Players who wish to purchase digital versions of Pokémon Sword & Shield should probably invest in a micro SD card for their Nintendo Switch (if they don't own one already), as the games are over 10GB in size.
One of the initial concerns about the Nintendo Switch following its introduction was the memory limitations. The Nintendo Switch only has 32GB of internal memory, which can fill up pretty quickly. Players who want more room need to buy micro SD cards, which is especially important for people who prefer purchasing digital games. Nintendo has offset these internal memory limitations by making sure that its first-party games have as small a file size as possible.
Pokémon Sword & Shield will be the biggest Pokémon games on the Nintendo Switch in terms of file size. A Twitter user named @MIN428 has revealed a copy of the box for the digital version of Pokémon Sword & Shield, which states that the file size for the games is 10.3GB. This means that Pokémon Sword & Shield is double the file size of both Pokkén Tournament DX and the Pokémon: Let's Go! games.
Pokémon Sword & Sheild have huge file sizes in comparison to the other games in the series, but they aren't the biggest first-party Nintendo games on the Nintendo Switch. There are games such as Super Smash Bros. Ultimate and The Legend of Zelda: Breath of the Wild, both of which take up over 13GB of space.
Pokémon Sword & Shield are the first mainline entries in the Pokémon series to be developed for home consoles, so it's no surprise that the games would be so big in comparison to the earlier entries in the series. This is also taking into account the fact that not all of the Pokémon will be in Pokémon Sword & Shield, which means that a future title that did contain every Pokémon could be a lot bigger, depending on how many made the cut for Pokémon Sword & Shield.
Pokémon Sword & Shield will be released for the Nintendo Switch on November 15, 2019.
