Hmmm, lets see last good Lucas Arts games... Jedi Knight, Grim Fandango, the Monkey Island series, uhm... Super Star Wars on the SNES. Hehe.

Oh, and I think they also made the greatest Adventure game of all time, Day of the Tentical (eg; Maniac Mansion 2). They should stick to what they are good at or just publish games--oh, wait.
