There is a Lego minecraft. It started as a video game thing where you can make your own levels out of voxels (cubes). Looks a lot like Lego though (blocky).
Guy made billions off of it. It went absolutely full goose viral. Cultural phenomenon. There's movies...documentaries...
It's literally legendary in the gaming world.
Made by a Swedish developer Markus “Notch” Persson and company. Microsoft bought him/it out for 2.5 billion...with a "B".
Minecraft - Wikipedia
It's huge. Think bigger than pac man or space invaders in terms of cultural "glitz".
