So there has been a recent explosion of Knockoff Lego sets, especially by a China company, Decool.
I just had a thought: Is the new Ball-and-Socket building system easier to imitate as compared to the old pin-and-axle system? It would be easier to get the ball socket right, as compared to pin and axle holes, as they can either be too tight ot too loose. Set designs too have gone down in intrinsicity, such that pieces are easier to imitate. Is this why such knockoffs have improved in overall quality and appearance?
What do you think?
