Manual games recently played: Invasion: Taipei (PRC invades Taiwan, includes a very good cyberwar module), Vietnam Battles (actually two games: Hue City and Khe Sanh, I played the latter), and Napoleon's First Battles (I played the Marengo scenario--a very see-saw game).
Computer games recently played: The Operational Art of War, Century of War edition (20th Century operational-level conflict, very detailed treatment under the interface, you can design your own scenarios if you have a detailed enough order of battle and maps).
It's only a matter of days before Civ III is released! Not a proper "Grognard" game, but one of my all time favorite games is Civ II, so I have high hopes.
