Toys aren't just for kids, just like fun isn't just for kids.
(In case you didn't get it: All of those words once meant or possibly still currently mean the opposite of the way in which they're being used in this comment. Language is what you make of it.)
It seems that you're approaching this from a mathematical logic standpoint - if we have a definition of A, then either each X is A or is not A, and since (1) definition of "toy" is based on certain characteristics and the set of "video game consoles" all have the same values for these characteristics, then they either are toys or not.
However, the things we're discussing here are based on subjective feelings and nuance, and are also recursive - in this domain, we assign the statement "X is A" a higher probability just because people in general agree with the statement "X is A" (think Wittgenstein's "meaning is use").
Using mathematical logic in such domains is not very constructive.
Just because something is for one group, doesn’t mean that it’s illegal for another group to use it.
Yeah, I think the Switch is for children. I think it’s designed to appeal to kids and be sold, primarily, to kids. I also think that a lot of adults appreciate it regardless because a good toy can appeal to more than just the young.
If you think adults can gain no value from a toy, you are definitely not living the happiest life you could live.
So the more sandboxy a game is (Minecraft) the more it is a toy, but the more you are on rails or limited in what you can do (Tetris), the more it is a game.
No. This is, in fact, the point of contention here. I've heard ads and people calling boats, cars, tools, new games, and so on toys. A few dictionaries I checked agree. Several people in this very thread have the same opinion.
