Don't get me started on Legos today.
Too expensive, and too restricted to building one thing, and buying another set and another and another.
When I was a kid, you got a gigantic set of Legos, and it came with a book with about 50 things to build. You build a bunch of those, and you get the hang of building your own things, and have the pieces to do it.
Now you buy a specific "scene" from a movie, there's only one way to build it, and you don't have the pieces to build anything else. 80% of the pieces are orc arms or pirate masts that don't have usage otherwise. And there's clearly a "right" way to do it. Even if your kid could build something else wacky and stupid, it wouldn't be the "right" way, and kids know that.
It's just expensive model building. Spend $50, follow instructions, build the unit as proscribed, and move on to #2 of 38 in the series.
Don't get me wrong, my son loved them. He got very good at following directions, which is certainly a skill that all good worker drones need to have.
But it is absolutely not an imagination building toy in any way any more. It's a finely tuned mega brand focused on nothing more than compelling you to buy ever more product.
