Nostradamus is a game with a fairly average story, repulsive gameplay, some impossible to solve puzzles, poor graphics and some fairly bad voice acting. In the game's defence, YARS didn't find any obvious glitches, which have been ominous in the other lighthouse games they have played, and if you can look past the gameplay, it's got some fairly good murder mystery elements to be found.
Unfortunately, there was not enough good for them to be able to look past the bad, and they found the game generally boring and frustrating. YARS would advise you to avoid this one unless you desperately need to play an adventure game and can't find anything else, in which case, try the demo first. There are much better adventure games to be had.
