And honestly the pieces aren’t even that easily reproduced. Our son got a knock off brand as a gift and it was horrible to build compared to a LEGO set.

  This is actually a trade secret of lego. They build to such tight tolerances that others cant compete in the interlocking... it is a known thing of theirs, and honestly - we should be building that into actual construction mediums

    They also have the exclusive patent for the raised dots being slightly dome/cone shaped so any competitors are doomed to be worse no matter how well made.
