Not really sure why whenever a game gets an adaptation and it strays from the original concepts, the immediate excuse is "aimed for kids". Im sure the original design would do fine too. My 2 year old son, was with me in Best Buy was in the amiibo section grabbing as many as he can, saw Mega Man smash amiibo and dropped every last one of the other ones to grab that one.
That being said, this could have been MUCH worse.
