So by this point we know that Mario Party 10 supports amiibo, and that it reads and writes data to the amiibo, which makes it the only game to do so other than Smash Bros.. Though it seems if you're intent on not buying the same character's amiibo twice, you're screwed if you want to keep your Smash Bros. data. In Mario Party 10, scanning an amiibo on to the Game Pad will unlock an amiibo board based on that character. You know what that also does? It deletes your Smash Bros. data. Wat. Now, we knew from the start that amiibo will only store data for one game at a time. But Mario Kart 8 and Hyrule Warriors also possess a similar function, unlocking content but without the forced deletion of Smash Bros. save data. The alleged difference here is that in Mario Party 10, the game writes data to the amiibo by saving your personalized board layout to the amiibo- not to the console. It could have saved to the console's system memory, but Nintendo a.) wants you to suffer, and/or b.) wants you to buy another amiibo of the same character. This is not ok, Nintendo. I just want to have every board at my disposal- while still being able to retain all my level 50 Smash Bros. amiibo. Is that really too much to ask? No, Iwata, it's time you tried to understand me.
