You will be able to get the digital version of NBA 2K18 for the Nintendo Switch but you’ll need to have a micro SD handy in order to save the game file. Each save file for the game takes 5GB and the game itself is 22.9 GB. Other games for the system on average take up to 3.2 GB. Bad enough that the system only has 32 GB internal of internal memory.
The physical version which will be 6 GB and you still have to add another 16 GB for software update so you’ll need a micro SD to handle the larger sized file regardless of which version you end up with.
Not surprised that this is happening when the Switch was announced to only have 32 GB of memory. In 2017 we shouldn’t be having issues with lack of memory in consoles so for those of you that has to deal with that struggle, we applaud you for your bravery.
