This game was a lot of fun for me, but I also consider "The Colonel's Bequest" to be one of my favorite games, so if you enjoyed that game, you will enjoy this game. The inspiration is evident in the overall look and feel of "The Crimson Diamond," but there are also modern improvements over the classic, such as an auto-save feature, keyboard shortcuts for exploring and questioning suspects, plus a list of your objectives and clues, so you always know what to do next. You might even learn something about geology and mineralogy along the way. I played this on Steam, as a release on GOG was unknown at the time, and loved every minute of it. Haven't played "The Colonel's Bequest?" It's conveniently available right here on GOG, along with its sequel, "The Dagger of Amon Ra." No go out there and help Nancy Maple solve the mystery!
