I think amiibos are bad for the environment, just like K-Cups or Skylander figures. Not everyone is a collector, so my guess is that a bunch of those will be pitched and the amount of plastic waste will skyrocket.
That said, I don't -hate- amiibos but I do -HATE- the impact they have on the hobby of video game collecting. People who legitimately wish to collect them but missed out will be SOL unless they want to give some scum-ball, f*cktard on eBay (a website I grow to hate more and more with each look) a ton of money that could be used for other video games. These people should be ashamed of themselves.
I know of no one on here doing that (yet) but, those are my two cents on the matter.
