Draclvr, I have more games to add if you're interested.
I haven't gotten around to playing all of my old games yet, but I am working on it.

I have tested both Secret Files games just a little past the introduction. So far, they have been working smoothly on my Win 7 64-bit.
Games I have completed:
The Longest Journey (had to disable 3-D acceleration before installing patch)
Grim Fandango (had to install launcher)
Escape From Monkey Island (had to install launcher)
Gabriel Knight 1 (with patch)
Gabriel Knight 2 (with patch)
Gabriel Knight 3 (runs perfectly)
Syberia (has some sluggishness during conversations with the rectors and hesitates before one or two cutscenes, but other than that, runs fine)
Syberia 2
Journey to the Center of the Earth (download version)
Memento Mori
Sinking Island
Perry Rhodan
So Blonde
A Vampyre Story
Still Life (had to run in NT 4.0 compatibility mode)
Everlight
Murder in the Abbey
