Hey, wait a second! How could you not mention
the Curse of Monkey Island as one of your Lucasarts favourites? One of the things that I like about the game is that every screen, no matter how trivial, has a soundtrack dedicated to it. (I believe that this also existed in the Discworld game, in which one of my favourites is heard in a shed.) And many screens had several soundtracks as well! And one cannot forget '
A Pirate I was Meant to be.'
