Necronomicon: Dawning of Darkness is a point-n-click horror adventure full of creepy environments and characters. You are William Stanton, an archaeologist, who gets pulled into a nightmare by your friend Edgar Witcherley. Edgar is crazy and you must find why. You have to investigate different places and look for clues to progress. Most of the riddles are very clever, but a few are just obscenely difficult. One or two require more trying than thinking, which is annoying since you have to point-n-click to move places. None of the puzzles are easy, but most are good and solvable without a guide.
Graphics. They are good if you play on a small screen, but big screens make it hard to see some items. The Bungalow level is awesome but it is very dark and hard to see things.
Ending(s). Is it worth it? Ehh. I believe the PC edition has two endings, but the PSone only has one. I would say this game should be played for the puzzles and adventure part, not to see a great, long ending.
More. It is two discs and kind of long. But figuring out the puzzles on your own is rewarding since they will probably take a while. It is the hardest game I've ever played so far.
