While Lego Batman and Lego Rock Band have tempted me, I've always stuck with the regular versions of those games rather than diving into any block-based variations. But nevertheless, I sat down to check out TT Games' latest Lego outing, Lego Harry Potter: Years 1-4, with an open mind -- I have read and liked the Harry Potter books, and seen and enjoyed most of the movies. Maybe actually seeing Lego Hogwarts in action would win me over.
