Your wish is Nintendo's gift to you. Nintendo will release memory card versions of the Amiibo. So you can just have a card that you swipe to get the Amiibo functionality in the game. You don't have to buy a little figure for Amiibo in game functionality. This will come later this year according to Nintendo.I'm just going to be honest here and say I loathe the Amiibos. I hate everything about them–their look, their function (which still baffles me, admittedly), even the sheer number of them. Nintendo seems to get a bad rap for its 'kiddyness', and know I shouldn't care what people think, but truth is, I sorta do. The Amiibos look like bona fide dolls or action figures, in my opinion. They're good for that niche audience that's into that sort of thing, but they may not be everyone's cup of tea. I personally would've preferred some sort of memory card-based thing with some sort of neat design that functions like the Amiibo–or at least as an alternative to it. That aside, I might be willing to get an Amiibo if for whatever reason they released a Gonzo (TWW) or Alfonzo (ST) one. (;p)
It's good for people like you who do not like the Amiibo figures and for people who want two different game Amiibo save files on the one Amiibo. Can't do that. But for the 2nd game Amiibo dave file you can just buy a cheaper Amiibo card for that.
