I have an O3DS XL with like 4 GB of storage on the SD Card. I just bought Bravely Default and the game took literally everything. I plan on upgrading to the New 3DS XL soon, but I also plan on upgrading the storage. Would it be wise to go over 100GB, or should I buy a 64GB Mini SD card? I plan on buying more games but the fact that one game took over 3 gigs makes me think what storage amount would be best.
