Dammit Nick, Blockland is a building game which, to me, is all/most game genres combined. I am very sure that Lego Universe, as Badspot said, will feature free building like Blockland. For example, I am sure that you won't just log in and find a spot to build in LU and chat with others around who are building in different lots around you. LEGO wouldn't let that happen considering that kids as low as five could be playing the game. Blockland, in my opinion can fully be considered a Mature to Adult game due to its free build/chat and sandbox nature. People could say or build anything online and thats why. Of course on the other hand, if you couldn't say anything (probably like LU) Blockland wouldn't even be 1/2 as fun to me, and probably lots of other players. Lastly, I don't think that LU will feature the scripting ability like Blockland does. Of course these are my predictions which I can't confirm at the moment.
