Thank you for such a detailed comment!
2-in-1 is actually something I forgot about. Though, technically and subtly, it can fall under “functions”. The box art isn’t that important I think, especially for those experienced fans that know how Lego sometimes cheats on box images. Cost is something I don’t usually count, because look at it this way: if you have two sets with same prices, but one is all about functions and stuff, but somewhat messy though and another one is mostly static (building etc.), but is incredibly beautiful, which one would you pick? It’s like judging not quantity of a feature in a set, but saturation of given feature in the set.
Ah. Yeah. That’s really important and I of course forgot about it…
Maybe, absolutely wierdely, we can put it in Collectibles section, as if the whole set was one big Collectible.
Wow, that’s strong. And building experience is yet another thing I haven’t thought of…
I see now what you meant by “Other”, and that helps a lot, thank you again.
It is actually quite interesting thought about backstory. As it is sometime not important what set is, but what it represents. Actually, the case with many Binicle sets: For example, Toa Mata are not so great sets by themselvesc(articulation issues mostly), but at the same time they are ones of the best, as they represent first, the most classic Toa form. It’s something Slizers (for example) lack.
