@AbdoooooWell it looks like the amiibos basically just use the Smash portraits as inspiration, which is why Luigi has that super weird falling down pose.
Also if anyone is a GCU member at Best Buy, your discount applies so they should only be at $10 before tax for you. I'm tempted but I just don't know....they look super cool so they're awesome from that standpoint. They just seem a little low in value in the game department, at least for right now. And I know I'd feel kind of slighted that I spent $10, and if I want even more of this bonus content, I'd have to shell out another $10...and then another, and then another.
I'm more or less resigned to just getting one because it looks cool, and if it adds anything to my games, then that's fun. I can't look at it any other way and feel good about the purchase.
