I complain for two reasons:
1. Damn, those things are expensive in a group.
2. Give what you get out of Skylanders and Disney Infinity figures, amiibos are comparatively boring, IMO. I get they work across multiple games, but every game but Smash (like MK8 and the upcoming Yoshi's Woolly World) is just a character skin. I'd like to see them get sandboxy, like Infinity, where amiibos can be interactive in something. They could have made them playable in MP10 (though given how poorly that game allegedly turned out, it wouldn't have been worth the effort). They could be Mario Kart 8 characters. They could be in Splatoon, or even Mario Maker (they'd actually make a LOT of sense in that game, IMO). I just think that they have unlimited potential, and it feels like they're wasting it.
But it wasn't even really a complaint, just an observation of how expensive that's going to be for true collectors (thanks to the secondhand market and hoarders, to an extent). I'd love to see amiibos work interactively across multiple games, but that seems unlikely to ever occur, partially because of the save limitations they have.
