Lego sets aimed at children are still good! They work as standalone toys, and can also be reassembled, modified and combined. Very few toys are like this.
Adults collect them, true, but there are whole lines dedicated to them.

The Game Boy was much more affordable. Less whimsical, but brought back memories of taking apart electronics and marveling at what these circuit boards and components could possibly be doing.
Edit: now that I look on EBay building my own display like that would probably cost maybe $60 vs $189? Broken Game Boys are $40 on eBay, so maybe a project I could do for fun!
These aren't being bought by kids and if the entire market becomes nostalgic adults, eventually they all die.
