If you are thinking about downloading Pokemon Sun and Moon then you better go out and get a bigger SD card as both games come in as heavy weights.
Pokemon Sun and Moon are 3.2GB each and the standard card that is given away with the Nintendo 3DS is 4GB. While the game will fit onto the SD card there is going to be very little room for anything else. If you wanted to download both games there is no way they will fit onto the standard card.
Nintendo also said that people who have played the demo version are not going to be able to transfer data onto the bought game. So this means you are going to have to start playing again. This is down to the fact that the standard card isn’t big enough to have both the demo and the bought game installed.
Pokemon Sun and Moon is larger than Pokemon Omega Ruby and Alpha Sapphire, which were 1.8GB each.
But what do you think about having to buy a new SD card to download Pokemon Sun and Moon?
