The debate seems to be coming down to where do you place the non-action figure Transformers toys.

It's like there's three tiers of collection, rather than two
1 - Transformers (the toys representing individual characters)
2 - Transformers-themed toys (skateboards, puzzles, Rubik's cubes, etc)
3 - Transformers-themed merchandise (backpacks, books, clothes, etc)

Therefore it becomes a question of where do you place Category 2.
I personally consider it part of Category 3, as they are more merchandise around the concept rather than the toyline that was about heroic Autobots battling evil Decepticons.
