If I had gotten platinum, and had chose NES Remix (which is exactly what I would have gotten), and then Nintendo decided "Hey, we are gonna release a combo retail package", I would certainly be a little annoyed, because I could have chosen something else and waited for the 2 pack of NES remix instead of having the 1st game twice.
Is the 2nd game available separately on the eShop or retail?
If not, then I agree w/ ejamer that Nintendo is just fumbling the easy stuff that they should be getting right, but always find a way to screw up.
