Games in my short list (after what you are already named, and Kyrandia too, and some - not all - Sierra for me):
Myst series.
Grim Fandango (actually,
any LucasArts adventure will do - they are all great for me).
DeathGate and all other adventures from Legend. Text ones (like
Spellcasting or
Gateworld) can be somewhat tricky, though, but "mouse" ones are great.
Longest Journey series.
Blade Runner and
Last Express. Totally different in gameplay, but very similar for me in "puzzling" design - it's not possible to see everything in one run!
Hmm, I think, that's all for me...
...Ah, wait, there is also
Simon the Sorcerer series!
Now that's all.
