Mario 3D Land was pretty great in 3D. For me, it made the platforming easier and more fun. I'd put ALBW in second place though. Like you, I ignored it for everything else.
I love the case. Everything snaps together very securely. I've had so many PS4 games come loose in shipping. I don't foresee that happening with these cases.
Yeah, once I heard about the Joy-Con issues I just ordered an extra Pro Controller. I'll be glad to use Joy-Con when a game really takes advantage of them though. I loved the motion controls in Pikmin 3, for example.
