TT Games has been at it for some time now with these Lego-themed games, taking on everything from Star Wars to Rock Band -- each entry sharing the same thread of goofy, self-referential comedy and low barrier to entry. The new trailer for Lego Harry Potter: Years 1-4 takes these recurring tropes and adds them to the world of Hogwarts, Muggles, and He-Who-Must-Not-Be-Named, sprinkling in iconic moments from the first four books throughout. With the first half of the final Harry Potter film hitting theaters next November, though, we worry it might be awhile before we get our hands on the block-breaking version of Harry.
