Lego City: Undercover hides an Easter egg. There are advertisements with a Sherlock Holmes picture on them. Traveller’s Tales could have teased a new Lego game or could be only a joke for the players.
In the picture we can see Sherlock Holmes with London in the background.
Joke or not, Sherlock could ample the Lego world and introduce a new gameplay in the series with sophisticates riddles and a different storytelling. It could be a different Lego for different players.
On the other hand, I would like to recommend Sherlock, the BBC TV series. It’s a new build for the character setting in our days, a modern Sherlock with modern challenges. Benedict Cumberbatch is fucking awesome, he deserves to be Sherlock, more than anyone.
