Summary: I assumed it was compatible with 3DS because most DS games can be played in 3DS (at least I haven't found any that cant - until now). Its not compatible with 3DS which would have a been a nice thing to have in your description of the product, unless the company is hoping that consumers will purchase this product and not want the hassle of returning it after they find out it does not work on they system. Good way to make money and deplete the inventory.
Summary: I had no trouble ordering it and dealing with the buyer, but I never recieved it. It was believed to have been lost in the mail. I did get a refund, tho I would have prefered to have gotten the game. I will still use amazon.
