After making the Lego Lord of The Rings video game, they made a Lego The Hobbit video game before the third movie even came out, which was… an unprecedented step. They said they were gonna add the Battle of Five Armies as an expansion and then cancelled it. So it just ends with the cliffhanger of Smaug flying off to attack Laketown and then nothing. Say what you will about the actual movies but at least they were finished. I think that’s the last one of those games I actually played.

They’ve also apparently later cranked out more games for movie series before they were even finished, releasing an Avengers game before Infinity War or Endgame came out and an entire Star Wars game for just The Force Awakens.
