I think it's important to clarify the rules because if we don't, we might get someone who overdoes it. Gashapons fit in my opinion because they're not huge statues that would clutter up the board, not only that but they rarely come up. A lot of them are articulated and largely considered to be accessories for toys, mostly Figmas or 1:6th stuff like consoles, food, etc. I think the toys-to-life stuff is also fine because while it's not necessarily a toy, it's manufactured by toy companies and targeted at the same audiences are other products at home on the board. The one area where I'm glad we don't have any overlap, and the most important topic at hand, are expensive statues created by the same companies who bring us the products we buy in the normal course of a day. For example, Kotobukiya makes excellent model kits but before they ever messed with those, they did statues and ONLY statues. The reason, in my opinion, that we keep statue separate from toys is not the typical answer, statues appeal to a very specific type of consumer, the /a/ crowd who watch tons of anime. When I think toy, I think product used or purchased by younger people. Statues don't fall into that group. As for gunpla, they are enjoyed by many age groups and are essentially DIY toys really so I feel they have a home base on toy as well. Same with scale model general where I spent all my time.
I realize my opinions don't adhere 100% to the board rules beyond a shadow of a doubt, I feel like I have a good feel for the board and have been there for a very very long time.
