Other creative toys/products that come to mind would be, say, Play-Doh as a sort of children’s intro to…Clay, I suppose? But in this vein without being exclusively directed towards children (albeit I imagine many may be).
Always enjoyed a creative kind of toy to mess around with.
A ton of videogames fall into this category. Minecraft is probably the most well-known, but any game with a base building element is a quick hook for me.
While videogames are great, a hobby that dabbles with real things will stimulate you very differently. Touching stuff with your hands, the gap between what you want and what comes out of your work, the search for materials and techniques and other aspects of working with real stuff and not on predefined paths, will engage with your brain in a very different way.
Videogames and “real” hobbies (as in hobbies that use real stuff) are great together in my opinion, they complement and fuel each other.
If you are a technical person, videogames can give you things a physical object cannot do. Minecraft with BuildCraft was so fun, engaging and stimulating in creating automated factories
