So, I went out the other day and bought myself a brand new copy of Hyrule Warriors. However, when I put it in my 5.5.1 Wii U and tried to open it an update started installing. For obvious reasons, I hit cancel as soon as I saw it and was notified that I won't be playing Hyrule Warriors until the update was installed. Both my Wii U and the copy of Hyrule Warriors were Australian. I couldn't find a date of manufacture on the game, so I have no idea how new it really is. My console was NOT connected to the Internet. Basically, my question is: Is this a new system update (5.5.2 or 5.6 or whatever) or is it just a game update? Is it okay to let it install? Answer: It was a game update. Nothing to worry about!
