I did. I get 10 or more streetpass per day at my college, so I figured that it would be waste to not have them with those numbers daily. I got all four at once for the discount. A long term investment for me.
Portuguese always gets shat on. I feel bad because it's my ancestor's language. The only games I have that translates into Portuguese are MK7 and NSMB2. The others just stay in English. I wish we had as many language options in NA though. The only interesting one is French. Spanish is so common it's boring. None of the downloadable eshop games like Pushmo translate.
