I can recommend
Realms of the Haunting. It's an action-adventure, many puzzles, many creatures to kill,
very atmospheric, good story and it's abandonware by now. I wouldn't go with the underdogs version though. The original comes on 4 CDs while the underdogs CD-rip version has only about 32 MB. Something must be missing there and if it's the cinematics then forget it, as that's how the story is told through many videos.
