Trivia: LEGO Universe
- Development Hell: The game was originally set for release in 2008, but it didn't actually get released until 2010. See What Could Have Been below for the reason why.
- Hey, It's That Voice!: Patrick Stewart narrates the backstory intro movie.
- Name's the Same: "Jimmy Changa" is one of the suggested phrases for the chat, suggesting that Jimmy Changa was the name of an NPC who never saw the light of day. Interestingly, Jimmy Changa is the name of a LEGO Soccer Mania character based on the LEGO Adventurers line. While it's possible that the LEGO Universe Jimmy Changa might have been intended to be the same Jimmy Changa as the one in LEGO Soccer Mania, since we have no confirmation on the subject, it's most likely an unrelated coincidence.
- Some of LEGO Island's more cynical fans might argue that the LEGO Universe Sky Lane is not intended to be the same character as the Island Xtreme Stunts Sky Lane, and the fact that they share the same name is just coincidence. Many others, however, believe that they are the same character and it's not just Name's the Same.
- Recycled Script: The unreleased player-versus-player LEGO Kingdoms "Captures the Princess" minigame would have been a recycled version of an earlier Forbidden Valley Siege minigame revolving around pirates versus ninja.
- Screwed by the Network: Despite reportedly having over two million players, LEGO cancelled all future updates in November 2011 and shut the game down for good in late January 2012. Nobody knows the exact reasons why LEGO cancelled it, but the fact that LEGO is now developing two new MMO games makes one suspicious that LEGO did not want LEGO Universe in the way...
- What Could Have Been: The entire game was redesigned in late 2009, nearly from scratch. When compared with most other LEGO games, the early design was Lighter and Softer then average, and the redesigned game Darker and Edgier.
- The redesigned darker game was also made easier. A common early complaint was that the game was too easy and too short.
- Before LEGO Universe was cancelled, the next update would have featured the return of Frostburgh and the release of the Fire Temple, complete with a boss battle against Lord Garmadon himself. Other worlds in the works include Ninjago-themed properties, a Ninjago Earth Gauntlet, two other Ninjago dungeons themed around ice and lightning, respectively, and an entire world based on LEGO Kingdoms, complete with a recycled PVP map from the game's early development days. The final trunk build of LEGO Universe showed other soon-to-be-released features, such as vendor dialogue and customizable hair options. And all this will never see the light of day because LEGO Universe got Screwed by the Network.
