Assuming that's an autocorrect typo and you meant "Wii U"… Your friends list is currently exclusive to the device, not to your account. They aren't unified. So if you add a friend to your 3DS, that friend won't show up on the Wii U, and vice versa.
No, I only have the 3DS but wanted to add friends from the users here who have it. Saw you and stitches had your Nintendo ID listed but wasn't sure if I could use that. I'll have to post my friend code then.
This hasn't been posted in a while, but I figure it's here for a reason. Xbox One Tag: smorse I play Madden 17, GTA 5, Battlefield 1, Black Ops 3 and am looking for decent folk that can deal with my novice skills.
This is indeed still an active thread, even if people haven't posted on it in forever. First post updated.
