I mean this is just a Nintendo thing. They always create artificial shortages. Fire Emblem Awakening was hit hard when it came out. I was thinking about picking it up, but everywhere online and instore was out of stock so I just gave up and forgot about the game. I think I asked for Link Between Worlds for my B-day instead.
Same thing for Pikmin 3 on the Wii U. I didn't pick it up the month or so it was released and when I checked, same problem. I eventually found it for a decent price, still pretty steep 2 years later. Then in 2016ish, a year later, they released it as a Nintendo Select...I hate them sometimes.
