Honestly, from a standpoint of "not capitalizing on an insane set of IP in videogames," the only company that baffles me more than LucasArts is Disney. And Disney is at least aware of the problem and actively working on not only owning its solution, but expanding on it with new game-original IP.
LucasArts is kind of like its founder; a huge initial showing with great promise, only to squander it in the follow-up and a failure to continue adapting. They also had some tremendous titles unrelated to the Star Wars license, like Full Throttle, Sam n Max, Maniac Mansion... hell, Bioshock's biggest minigame was a straight-up clone of Pipe Dreams, and Ballblazer would even now make a pretty good 5 dollar downloadable game on current consoles. The older SW titles were not only excellent representations of the game, but technologically innovative as well.
It is hard to know how LucasArts can sit squarely in some of the most desirable properties in the world, in the most livable and hiring-rich region of Silicon Valley, and manage to fumble ball after ball.
