i thought it was fun for a little bit but i wasn't even interested enough to participate in the last day of the server being up lol
the building was cumbersome and limited, everything was laggy and buggy and it was a total grindfest. the only thing i liked about it was the character customization and playing with other people in big groups but beyond that, it just wasn't worth it
there were better games then and there are still better games that feature character customization, excellent building, little to no lag, enjoyable gameplay, and large groups of players at once such as blockland, lego worlds, minecraft, and even roblox.
there's nothing special about lego universe other than "muh nostalgia" for something that was trying to popularize "hot garbage" as a game genre. Despite this, I will admit that the soundtrack was VERY well done.
