Well, seeing as how there were already quite a few different threads for amiibo (waiting for new ones, custom amiibo, amiibo displays, amiibo farming, amiibo training, and many others), it seems like they warrant more than just one thread, since they have quite a few different facets to them as compared to, say, Smash development history, which really only has one thing to talk about, that being, well, Smash's development history. Amiibo have a lot of things to talk about, or a lot of topics, which can't be fully covered in just one thread. They seem pretty popular as well; tons of people on here are hunting for them. But that's just my two cents.
