I have my 1 user for the Wii U but certain games require to play with no NNID. How do I create a secondary user that does not have an NNID to play those games?
Create new user then don't link to nnid
when you created the primary you link it but haven't confirmed it with email. when you create a new account it will ask you if you want to link with NNID. select no.
