Thought I was pretty good at using Google but could not find a real answer about system transfers.

If I buy a used 3DS that has digital games on it. Then system transfer from my 3DS (that is linked with NNID) do the eShops merge? Meaning I get those games on my eShop list. So I could then go back to my limited edition console with the digital games in tow?

Nintendo's account stuff is so weird. But I guess might allow selling digital games.

I feel like they're just going to do some DLC.  Either with Joel when he was a bandit or Tommy's story, maybe even Ish.  But I really hope they leave the future alone.  I don't see where the story could go

I have all the multiplayer dlc downloaded but I can select any of the new maps in the selection.  Do I need to unlock maps too?

I have a 5 screw flat top and a 3 screw Legend of Zelda and the colors are a little different. Is there any gameplay differences? Is one more rare than the other?
