I apologize if someone's already inquired about this as my access to the internet is limited and I don't have the time to search through a lot of threads.

With regards the Wii U update that must be performed on the day of purchase, is this update strictly for online features, or is it impossible to even play a game until you perform this update?

Just curious because I want to buy a Wii U soon and if that update is necessary in order to play games I'll need to come up with a plan to take my system somewhere to get the update.

Thank you in advance for your feedback.
