I switched from a 3DS to a XL because of this…(r/3DS)
As a fellow owner of the Zelda 3DS XL, I highly recommend that you get the Hori TPU case and some screen protectors to go along with it.
No matter how careful you are, your 3DS is bound to take some degree of damage eventually. This case does an excellent job of protecting it from normal bumps and wear (it won’t do much if you drop it, but that hopefully wouldn’t happen) while still showing off the design. Screen protectors are just good to have.
An additional note: I also suggest getting some sort of cleaning cloth to put between the two screens when you close the system: the bezel on the touch screen will scratch up the top screen.
