Yes, these were some of the best games produced, I have most of them for both the Amiga and PC. Now I'll look at the link Twistin' provided and see what's up.
Some notes to add:
LucasArts titles starting with The Dig I believe, also included the INSANE Animation System along with the iMUSE Sound System. To tell you the truth, DOTT and Full Throttle have great voice acting along with with great sound effects
