I actually just finished The Longest Journey. Amazing game, and I was stunned by its quality considering the time it was released.
I haven't played much point and click games at all though. Broken Sword was among those I actually finished. Another one was something I downloaded off the internet, it was a remake of an 8-bit classic I think, and pretty good.
I've also played Escape from Monkey Island and Myst but never bothered to finish them (more because there was still no home internet available at the time, so I had nowhere to turn to when I got stuck).
Still, I have moved on from those games though. They are still entertaining, and feature some of most amazing storylines in gaming, but yeah... they kinda pale in comparison to modern game graphics.
