I can't say that the graphics are the best I've ever seen - the backgrounds are gorgeous but, with a lot of things, expecially the people, you'd think the game designers had never heard of a curve in their lives.  However, the game itself made me forget about all that.  Gabriel Knight is his usual chauvanistic self, but, in spite of that, his relationship with Grace is further developed in this game.  The puzzles vary in difficulty, but I never felt as if any of them were impossible.  It's easy to see that a lot of research went into the story in this game, and, after finishing the game, I was interested enough to read some of the books they got their research from (there's a bibliography in the game's booklet).
