Topic: Will Multiple Nintendo ID's on Wii U Cause Problems?

We have 5 users on my Wii U. Mine user is the only one with a Nintendo ID linked to it.
When my son wants to play Call of Duty online, he has to use my user, because Call of Duty requires a Nintendo ID linked to a user to play online.

Several questions:
Should I link the Nintendo ID to my son's user on the Wii U?

Or, should I create a new Nintendo ID for my son?

All our digital games (smash bros, mario kart, art of balance) were purchased with my Nintendo ID. If I do create a new Nintendo ID for my son, and he signs in with his new Nintendo ID, will he not have access to the digital games we purchased with the other Nintendo ID?

Are purchased digital games tied to a Nintendo ID account?

Thanks in advance for all your help

My advise is you make a Nintendo ID just for your son. All the games you've downloaded on the system are available to any other user on the system whether they have a Nintendo ID or not.

The only real concerns with profiles and ID's are what will happen to them in the future. I got a Wii U only a year before moving out from my parent's. I bought everything myself, but my parents played a number of games too. The problem is there's no way to move just their profiles and data to a new system. Ideally, it would work something like it does on Xbox and PlayStation. They'd just buy their own Wii U and move their data from my console to their's, leaving just my profile and games on my console. But right now that is impossible. All profiles and data have to be moved together from one Wii U to another. So, depending on how old your son is and how much he likes the games on Wii U, this might be worth considering.

But that doesn't have much bearing on your original question. I don't see any downside to giving your son his own Nintendo ID. On my console, my parents and my sister all have a Nintendo ID's, and we've never had any problems playing games or keeping save data straight.

If you don't want your son buying games in the eShop, you can use parental controls to make that impossible. If you've saved any credit cards in the eShop or have any store credit, he won't see any of that on his profile. He'd have to enter his own information and build a credit of his own. If he does buy any games on his profile, you'll be able to play them too, but they will have been purchased in his name. If Nintendo ever does fix their profile migration system and your son ever moves his profile to a separate console, you will probably lose access to any games he has purchased, but that's just hypothetical.

Seconded. My 11 year-old daughter has a Nintendo Network ID; I make all purchases and that works fine. I'm not sure if NNID is required for Miiverse or not, but enabling the full "Wii U experience" was my motivation. My partner's kids occasionally come over to play and whilst it's never been an issue, I wanted to make sure her game saves were only accessible by her and the NNID is the only way to password-protect your account.
