Honeatly, whatever DLC aspect it has is extremely minimal. I mean I have close to 20 of them and I've only used half of them for games like Smash, MK8, Kirby, and Hyrule Warriors.
And until there's a real purpose to them besides collectables, like a Disney Infinity/Skylanders type game but for Amiibo. The main reason theyre being bought is for collectable purposes.
Hell, I even bought a basic Mario amiibo for my 3 year old little brother who has yet to pick up and play a video game in his life. (I'm working on it though. ;))

Because they're LQ figurines (not bad for the cost though). People need to hop on AmiAmi and how lovely and well crafted figures can be.

I just like the way some of them look. I'm not a fan of the ones that have cheap supports holding them up though. I like the ones without supports. Who the hell doesn't want to look at a Yoshi just chillen there in the entertainment stand?

Please change is to are in the title.

At least they are physical DLC always to be aviable in future Life, there is even a everdrive ammibo worked on because its offline based dlc

Only the first player needs an amiibo to play the game. Additional players, who have no amiibo can use the villager characters. The main game is fully playable with the 2 included amiibos. However some (two IIRC) of the seperate minigames require 6 Amiibo Cards and there are only 3 Amiibo Cards included in the game.

but those are for a specific game. They are tied to each other, it doesnt work without each other. Anyone buying those knows that. Now the way Ninty approached it is worse. I own Smash but do i really want to spend 15 on a figure with DLC of a costume? Not really and i imagine most people feel the same otherwise Ninty wouldnt bring it up. And how much people have a Wii U to even use the DLC. Hell you need a NEW 3ds to even use amiibo for that, and how many people own that?

That's false.

So, I have to spend even more money...

lol exactly! I mean i stand corrected, but who is really trying to jump through these kinds of hoops? how many people even know this exists? Cause i sure as hell didnt

And then, there's the worrisome part:

"our amiibo figurines are not the DLC we expect and nobody  finds value on them... let's lock more content in it!"
