I think Amiibo is a better idea than Skylanders or Disney Infinity, because they don´t take away anything important from the games they´re compatible with, with the exception of Mario Party and the horrendous Animal Crossing Amiibo Festival
Having a toy that can unlock multiple bonus in several different games seems a lot better than having a game entirely locked in a toy, like Skylanders, where you need a toy just to play the main game and several other to be able to unlock all the content the game has
In the end, the main proposal of amiibos is purely collecting. They´re toys after all. The funcionality may not be well balanced between different games, but being able to use a single amiibo in several games, even if just for small bonuses, adds to them a better value than other toys-to-life lines we´ve seen
That said, I´m fine with the way Nintendo has been handling amiibos. I just think that they could be somewhat cheaper and that they should avoid releasing the exact same amiibo in different colors, like they did with Mario, Mario 8-bit and Splatoon
