So I am a collector that likes to buy all different models of handhelds. I recently bought a 3DS XL and linked it to my club Nintendo account and bought some things on the eShop. If I were to buy a OG 3DS would I be able to also link my club nintendo account with it and play as well?
Yes you could link it to your account, no you couldn't play the stuff you bought on 3DS number one on 3DS number 2. All games and such are tied to the originating console until a system transfer is performed, sorry. Unlike the two Vitas my brother and I own, with one PSN account (since I don't play online) and anything I buy digitally, he can also play.
