How good are you at lying to your friends? If your answer is “Not at all!” then you had better get good and fast, because you’re going to want to school them at Diamond Trust of London — the new Nintendo DS title from independent game designer Jason Rohrer. It’s two-player, turn-based, simultaneous-decision strategy game about diamond traders operating in Angola in the year 2000, and whichever player can bring back the most diamonds wins. Naturally, this requires outfoxing your opponent with bribes, spies, and lots of general craftiness. Well, Jason, we see your diamond-mining-bribery-shenanigans, and we raise you a Project of the Day.
