Digital version of Hyrule Warriors is around 7GB
Hyrule Warriors is out around the end of the month, and those set on downloading the title instead of buying a physical version will need 7GB of space on their Wii U hard drive.
It's not a huge amount of space considering the size of other games, but according to Destructiod, you will need 7.08GB free.
In other words, the amount of free space you need will depend on whether you own the 8GB Basic or 32GB Deluxe version of Wii U.
Those who own the former, may want to just buy the disc version. Obviously.
Hyrule Warriors will be released on September 26 through retail and the eShop.
