X-Wing Alliance, Dark Forces (1 and 2), Rogue Squadron and Rogue Leader, and the single player campaign of Force Commander were all superb.
Shadows of the Empire was great at the time of release.
kotoR 1 was ultra cliche, if you've played any of the previous Lucasarts games.
Jedi Academy was wank... the multiplayer maps were outstandingly poor in quality and the singleplayer was just utter tripe.
Jedi Outcast has been the best attempt so far to match Jedi Knights legendary greatness.
Mysteries of the Sith was a fantastic expansion pack.
Star Wars Galaxies was the best MMO around till SOE screwed it up around patch 9.
Basically old school Lucasarts, before they stopped in house development was one of the best companies around, churning out such great titles as Monkey Island and Grim Fandango. Infernal Machine? >>>>> Tomb Raider tbh.
These days Lucasarts are totally different company. I'm glad they changed their logo lately - it makes that clear.
