The atmosphere (greek, egyptian and medieval settings, map design etc.) of the game is great. The soundtrack is one of my overall favorites. Puzzles are good and the story (texts, audio recordings) is a bit pretentious but pretty interesting in the first playthrough.
I've completed the game three times, I think, and have spent over a hundred hours playing it. Most of the time now I just walk through the game world and enjoy the design of the maps and the music to relax.
