I'm willing to bet that lego universe was created to coutner Blockland. Based on their features, designs, and what they say, it seems to have almost the exact same feature as Blockland. Other than the parent control thing and the building style.
Example:
They say you need plastic to build - Seems to me like the build cost we have.
and many others which I won't say.
Also, they said it's goign to be like all those Lego star wars, lego indiana jones, type games. The drop-in/dro-out, those ones. Who thinks that the game will suffer twenty billion kids and it will be crowded until it has to shut off the game one week after it was released.
