https://www.gamespot.com/articles/youll-need-a-microsd-card-to-play-nba-2k18-on-swit/1100-6453372/ >NBA 2K18 launches digitally today for Nintendo Switch, PC, PlayStation 4, and Xbox One (with its physical release for the latter two platforms arriving on September 19). However, those who intend on picking the basketball game up on Nintendo's console better have a microSD card handy. >As pointed out on NeoGAF by users Pokemaniac and ggx2ac, NBA 2K18 requires a hefty 22.9 GB of space to download on Switch. What's more, each save file for the game takes up 5 GB--a larger file size than many full Switch titles, such as Pokken Tournament DX, which only requires 3.2 GB to download. That's problematic considering that the console only comes with 32 GB of internal memory, roughly 25 of which are actually usable.
