My wife and I bought back into the “3DS Family”. Now we’ve had all of the 3DSes except for the New 3DS (not XL). We decided to get into Pokemon this go round.
I do have to say that even though Nintendo is odd in only allowing you to transfer your Nintendo ID login from one system to another if you have them both in hand, calling them and asking them to release the ID from the old system (that you presumably sold) is quick and straightforward. I don’t have the Ambassador games I got for free for being an early adopter (I guess they weren’t tied directly to my account), but I do have the game I paid for back (“Link’s Awakening DX”).
