im torn right now, because its troublesome to carry around a card case and the digitals are more expencive. by like 20 bucks. so I don't know what to do. being able to play bravely default whenever I feel like it is pretty amazing though....
Do whatever is more convenient for you and works best for you. Only you can decide that, we can't decide what is a better option for you.
Personally, I always prefer physical copies. I don't like having to save a bunch of game data when I could buy a physical copy of a game and use that memory space for other things. >>;;
