Amiibo

If I was rich, I'd buy every Amiibo. XD I'll likely skip out on those 3, although Little Mac does have a pretty nice looking Amiibo, so I might just go ahead and buy him.

As for Rosalina being Target exclusive, that sucks. I guess I won't be getting hers then. (she'd probably be discontinued the day after her release seeing how Amiibos have been going so far, lol)

Finally, a third party game has been confirmed to be compatible with Amiibo! One Piece: Super Grand Battle X will unlock costumes for the characters with the Amiibos. Not a game I care about, but still nice to see non-Nintendo games that still use Amiibo.

It was already announced Ace Combat 3D supports the Bowser amiibo Zero.
But at least they're allowing third-party games.

^ What? When did they announce that? I don't remember that. Regardless, I probably won't get that game either. XD I'm glad third parties are embracing Amiibo though.

This was done for the third wave.

^ Nice. I do wonder why they even show all of the Amiibos as compatible with Hyrule Warriors though, they just give a small rupee prize or something like that, it's not like each one has individual compatibility to do something different.

“We’re not making promises for certain figures, but the way “amiibo” is designed is that certain games can have “amiibo” specifically for that game. Other games can take advantage of past “amiibo” that developers want to make their game compatible with. In the future, we have the option, if certain “amiibo” figures are no longer available in stores, to release an “amiibo” in card form with the same functionality.”

Miyamoto said that in an interview.

Alright, so then why aren't we ONLY getting the cards? I guess the figures can be more of a collectable, whereas the cards will be for those who don't care about the way the visual appearance?

Here is a current list of compatible games:
Wii U
Super Smash Bros. for Wii U
Mario Kart 8
Hyrule Warriors
Captain Toad: Treasure Tracker
Kirby and the Rainbow Curse
Yoshi's Woolly World
Mario Party 10
Star Fox Wii U
The Legend of Zelda Wii U
Pokémon Rumble U

Nintendo 3DS
Super Smash Bros. for Nintendo 3DS
Ace Combat: Assault Horizon Legacy Plus
One Piece: Super Grand Battle X

^ Don't forget Miyamoto also confirmed support for Zelda Wii U. That's actually quite a few games, but I'm hoping there will be an Amiibo game that uses them all so they aren't all pointless outside of Smash Bros.

Also, these are getting increasingly rare. I just went out today, and the store only had Link, Peach, Pikachu, and Zelda. >_> I didn't purchase any myself, but seriously, those were the only 4 available.

I only saw Kirby and DK at Walmart. I just picked Diddy up at a out of town GameStop so now I only need Pit, Falcon and Mac. 

It was a bit strange though since the Amiibo where all locked up there.

I've since gotten Zelda, & Luigi right before I got Link, Peach & Pikachu as a part of my Christmas gift to me from my sweetie Jing. :3

I'm still short 3 amiibo's I want: Rosalina, Shiek, & Shulk but they won't be releasing until February of 2015 though.. ):

I think I've figured it out.
Ones like Captain Falcon, Vilager, Wii Fit Trainer, aren't being stocked much because they won't have lots of use like Mario, Peach, Link, Zelda, Yoshi, Kirby, etc.
So that downs my hopes of F-Zero Wii U.

^ You're probably right, but that doesn't down any hopes of F-Zero Wii U, or Animal Crossing for that matter. (and Wii Fit U is already out) If they get Amiibo support, maybe they'll actually get full support and not just bonus unlockables for having the Amiibos for Smash.
