I have one 3DS and one physical copy of AC at the moment, I want to make an additional town. Would buying another physical copy allow me to do this. I've tried playing the game on my brother's console and my town is in tact when I load it up on his, this leads me to think that the save data is stored on the cartridge, if this is true i'm wondering if buying a second physical copy will work. I've seen people buy both digital and physical copies but i've heard bad things about the save data still clashing with eachother. Anyone know how this all works?
