We couldn't have a list of great PC games for kids without having a building game on the list somewhere. Since the obvious one has been out for many years now, it couldn't be included, so we turn to the ultimate building franchise for this slide.
LEGO Worlds was released at the beginning of the year and brings everything you'd expect from a LEGO building game. The game features an open world with procedurally generated environments that you can fully manipulate. Kids can build whatever they can imagine by either moving things brick by brick or by using a prefabricated building and then customizing it.
LEGO Worlds is currently available on Steam for PC as well as on PS4 and Xbox One.
