I don't know if you have played the game "My World". Although I have never played it, but when I was in college, there was a classmate who was crazy about this game. I also watched it. When I saw him use one by one. When the small squares built a building of various shapes, I was shocked. I think this process of building a world of oneself is the key to their obsession with this game. If you switch to the real world, this similar gameplay is Lego, with a small part to build a variety of shapes. I am not a fan of music, but I am still amazed when I saw the ever-changing styling and world-renowned urban landscape model at the Lego theme park in Johor Bahru, Malaysia.
