They look really nice detailed but more toys and smartphone games might take Nintendo in a completely different direction than they once were. At least the older games will always exist.
Except the Amiibo barely contain anything. Extras at best. I mean, unless really care about sure things as leveling up and watching the cpus fight or Pacman helmets than the actual game. When you need an amiibo for something like classic mode or to unlock every character in SSB then I'll be worry.
Why can't Nintendo invest their time and effort elsewhere outside of the figurine department? Once again, no one wanted these, no body asked for these, and if these new figurines do take off, I think we can all deduce the reason why.
Rumiko Takahashi got so much fan email about the character that she brought her back in the manga, it was going to be completely different originally (with the alien of the week type).
