There is also fischertechnik, how popular is it outside of Germany?

The company website is almost a parody of the stereotype of serious German-ness. It is not a toy, no it is a serious learning material, so you can buy a 10000 Euro set to understand how an integrated factory is working:

There is a „toy“ section for children, but it is to learn about electricity or renewable energy, and I think the real customer of the page are not the depicted children, but the papa with an engineering degree.

How could I forget to mention fischertechnik. It was the third member of the three most popular toys in my childhood, next to Playmobil and Lego.

Other than Playmobil and Lego I have not seen toy fischertechnik for years, but I occasionally recognize their non-toy fixings.

Fischer was the most prolific German inventor with 570 patents, who amongst other things invented the plastic wall plug.

Not a good sample but I've lived in three European countries with my kids and I've never come across them before.
