So far this year:
Yoomurjak's Ring
Art of Murder 2, Hunt for the Puppeteer
Chronicles of Mystery: The Scorpio Ritual
Nostradamus
Sherlock Holmes vs Arsene Lupin (Nemesis) - replay
Shady Brook - replay
CSI Dark Motives
I loved all of those, particularly Yoomurjak and Nostradamus of the games I hadn't previously played.
I started but I didn't finish:
A Vampyre Story
Ceville
Ankh 3
I have a mental block with cartoon style games right now.

I also tried Mystery of the Druids, but the clunky dialogue system drove me bananas and I gave up quite early on. I may go back to it at a later date.
