Did you pre-order the basic 8GB Wii U just to download console exclusives? If so, you’re going to be disappointed. Nintendo has revealed the smaller models only have 3GB of space left once the system has finished downloading its mandatory installs.
This means you’ll be forced to buy external hardware if you want to install most titles. Even lightweight games such as the 3.2GB Nintendo Land can’t comfortably snuggle onto the device.
The Wii U will support up to 2TB of memory from drives that have an external power source. Nintendo has suggested USB storage can be used, although it isn’t recommended.
