I think it is in the best interest of this company--for which all backers should consider themselves board members--for development to focus as little as possible on gimmicks, especially gimmicks whose only purpose is to sit on hawkers' shelves and increase in value via artificial exclusivity. Amiibos are just fetishized DLC you can't download anyplace without dropping $100 to some hoarder in Vermont a week after it's availible!
All the things Amiibos are expected to do within the game can be done without the actual figurines. Playtonic needs to use all of its resources (time, personnel, and all capital) towards creating an engaging experience for every platform it is being released on. This is, after all, the company's first impression, past glories aside. Less gimmicks, less outsourcing, less pandering; more detail, more planning (especially towards puzzles and level cohesiveness/density), more gameplay innovation.
I.M.O.--But anyone can disagree and be wrong.
All Amiibo opponents seem to share the exact same concerns. I personally would love to have a figurine matching the posterior pose in the promo art. It's very cool. But I don't want to have to buy the figure...and the stand...and the cables when they break, for DLC that would cost me much less without the plastic. And what a b**** it's gonna be when a neighbor kid swipes the figure and I can't access the DLC anymore! All that stuff about pay-walls and development windows, too.
