Do you have an example of a one of those pieces?
I haven't had a Lego set in decades, but I do recall feeling that the ratio of fiddly pieces vs "foundational" pieces getting out of whack towards the end of my time with them. When my kids get old enough I suppose I'm going to have to get them one of those "classic" sets, because I'm not sure they'll be able to get enough by just collecting regular sets.

And stuff like that isn't new. I remember I had a "castle" set that had these wall-with-window pieces [1], which were kind of similar. You could still use them creatively. Also that waterfall set has a lot of pieces that would be good for building stuff like spaceships or planes.

At least that was my understanding in the mid-90s, when I worked in the toy industry.
I'm still conflicted about it. Though I can't deny the creativity on display at any LUG or brickcon, I greatly miss the simplicity. I own too much Lego and I've given up trying to rationally organize loose peices.
