Nintendo has revealed that if you want to download WWE 2K18 for the Nintendo Switch, you will need a memory card at least 32GB or higher. Without it, you won’t be able to play the game.
Nintendo announced on the official WWE 2K18 product listing the following: “ATTENTION: a microSD card (sold separately) with free storage space of minimum 32GB is required to download this game, plus 1GB on the system memory. You must have your microSD card inserted before beginning the download.”
The Switch version of the game is not out yet, but it is still going to be released in Fall 2017. A big memory card is important mainly because the game has a lot of data.
If you are downloading the game on other platforms, it’s worth saying the game requires close to 50GB of data. It’s a huge game since it has the largest roster in franchise history.
