Pretty nice puzzles! First game I bought with my own Money!
The graphics are pretty nice to. Difficult level is pretty good also. What one really has to ad to a review of this game, is that it is a sequel to "The Seventh Guest" also by virgin and Trilobyte. It adapts perfectly, and after a while you realize you will not have lived the real 7th Guest experience where there no 11th Hour to complement it this good.
The game has 4 CDs because it is heavily loaded with movies of the game itself which are played in the cut-scene. What really is an issue to this game is that the sound-card really is 100% compatible. I installed it 3 times, one with win95, win98 and XP. all 3 on different machines and the sound was not quite perfect.
I recommend this game, if you have the time to play a "totally worth it" oldie, this is the one you should choose.
