Nice. I've been waiting for this subject to resurface.
As someone who's put a decent amount of work into the Interactive Figures category, I would LOVE to see sub-categories for each of the major lines. As far as how complicated the sub categories get, I don't think it's really necessary to break it down by country like most of the other categories are.
Instead of this as subcategories like this...
Amiibo Figures [EU]
Amiibo Figures [JP]
Amiibo Figures [NA]
I think it would be easier if we did something along these lines where the figure entries themselves denoted their origin...
Rosalina & Luna (Super Smash Bros. Series) (AU)
Rosalina & Luna (Super Smash Bros. Series) (EU)
Rosetta & Chiko (Super Smash Bros. Series) (JPN)
Rosalina & Luna (Super Smash Bros. Series) (NA)
I would think this way it's less complicated and no more annoying than dealing with something like this...
Mortal Kombat X
Mortal Kombat X - Limited Edition
Mortal Kombat X - Deluxe Collector's Edition
Mortal Kombat X (Greatest Hits)
Me personally I would break down the section down like this
Interactive FiguresAmiibo Accessories (for things like stands/displays/carrying cases/etc)
Amiibo Animal Crossing Cards
Amiibo Figures
Disney Infinity Accessories (for things like stands/displays/power discs/playsets/carrying cases/etc)
Disney Infinity Figures

Skylanders Accessories (stands/bags/playsets/traps/special items)
