According to a game designer who worked on previous LEGO games, Lego Batman 4 is reportedly in the works at TT Games. More specifically, Stephen Sharples, the former Game Director at TT Games, has pointed to a recent observation that appears to have some validity despite being based on an earlier Fanbyte article.
Due to the success of Disney Dreamlight Valley, 'Lego Disney' was apparently canceled.
Sharples supports TT Games in a tweet, claiming an in-depth update on Fanbyte.
The comments continue, claiming that TT Games has "quietly cancelled" four additional projects internally. Regardless, it appears that the developer has its hands full with a new Lego Batman game (ostensibly, Lego Batman 4) and Mandalorian DLC for the Lego Star Wars: The Skywalker Saga.
According to Sharples in another tweet, leaks are a regular occurrence at TT Games, as witnessed during his tenure at the studio.
Despite what the critic claims, Lego Batman 3 was released in 2014 for PS4, so this may be a good time for a comeback. In fact, some people might find the LEGO series boring.
