Yes, the Lucasart's adventure games have held up really well I think. I still replay Grim Fandango from time to time and always find it great fun just for the characters and the fantastic voice work.
Beneath a Steel Sky is also good.
I recently (after much effort) got Tie Fighter and System Shock 2 up and running - those are two great, great games.
Try to be reasonable... its easier than you think...
