Everyone has no issue bashing on Capcom or other devs that have disc locked content, but Nintendo comes out and does the same thing and they're praised for it.
With various games, Nintendo will be releasing Amiibo for specific games, costing between $10-$15 each. The Amiibo will be required to use certain features in various games. The SSB Amiibos will allow you to save a growing AI, customize skill sets, and growing damage perameters of the specific character that t hat Amiibo represents. The data is already in the game, it's not like they couldn't have just had the option in game without forcing the player to spend more money to use it.
Let's say someone wants to be able to use this feature on every character in SSB. No idea how many characters will be in the game, but assuming Mr. Game and Watch is in the game, that's 34 so far. At $10 each, you'll be spending $340 at minimum. So SSB will be about $400 for the full game. This is much worse than anything Capcom has done with DLC.
