Are you saying it's not an assumption because it's an opinion? Those go hand in hand. When your opinion is on the reason for something, then it's also an assumption. Terminology asside, it doesn't change that we can't know for a fact what features would or wouldn't have existed without amiibo. As for your "fact", AI, character skins, difficultys, traditional party mode, and weapons that are literally in the game already have all existed in Nintendo games before.

No Zelda refreshing hearts, arrows or 4x greater dmg didn't exist in Zelda games before. Same goes for skins in Mario Kart, or controlling two Yoshis in Yoshi Woolly World..

I see you shamelessly moved the goal post, as you originally said "in any nintendo game." More importantly, you completely ignored the assumption part, which is crucial because if you can't accept the fact that we don't know whether these features would exist without amiibo or not, then I'm not going to continue on with you.

No, I do agree with the point people are making that these features wouldn't have been included without Amiibo. I certainly don't think the thought process behind these features is "What can we take out of the game and lock behind Amiibo", I do believe it is "What can we add to the game to give Amiibo functionality". That doesn't change the fact that it is essentially on-disc DLC.

Well, at least on the bright side, among a group of people, if one of them has an amiibo you can use, you can just borrow it and never need to buy one. Worked for me a few times, haha.

Already wrote, Zelda refreshing hearts, arrows or 4x greater dmg didn't exist in Zelda games before, same goes for skins in Mario Kart, Smash, or controlling two Yoshis in Yoshi Woolly World...that is a fact, Amiibo things like those bring to games, I really don't see Nintendo would include features like those in games without Amiibo.

Which is the reason for me not to buy these games at all. I do not buy incomplete games.

I'll say it once and I'll say it a million more times... DLC, in any form, is evil.

The Amiibo shenanigans is why I haven't bought a Nintendo title in awhile and don't plan on doing it any time soon.

No, I wouldn't say dlc is evil. It's a good way to extend the life of a game, though it's easily been turned into a bad thing these days... : /
