my wife was upset at the list of rewards for Platinum status on Club Nintendo. Nearly every game on the list we own in one form or another. She eventually went with New Super Mario Bros. 2 because she doesn’t have it on her 3DS whereas I do. We used to just share the 3DS then she wanted one of her own, but that was the only game we had downloaded on it, so she wasn’t able to play it on her system. However, when she went to get the code, they told her that her gift had already been redeemed. I’ll tell you, when my wife gets angry at Nintendo, she gets very angry.
I probably would have preferred Metroid Fusion or Advance Wars, although in all honesty I wish Nintendo would do more cross-platform download titles like Sony does. If I want to play a VC game I downloaded on one console that is available on the other, I should be able to do that without having to buy it again. My wife bought Final Fantasy IX on her Vita and was able to get it for free on our PS3.
