I know that it is possible to use more than one game with the App, but what about more than one system? My brother and I would like to share the storage since we won't be filling it up I'm sure. I'd rather not have to switch the game cart between our 3DS's just to use it, but does that seem like the only option?
And no this has nothing to do with $5/year being too expensive, I just think it would be more convenient, and I might as sell save $5 if I have the option.
Waiting for: Pokemon X/Y, Tales of Xillia 2, Super Smash Bros. U, Dark Souls 2, Wind Waker HD, Zelda U, Mario Kart 8, Zelda a Link Between Worlds, X, etc
