Battle Leader Tactics is a free card game with a unique premise. From the introduction:
BLT is a component and introductory game for the Battles Leaders Tactics & Technology (BLTT) master game. BLTT is an abstract wargame that depicts some of the greatest military leaders (e.g., Alexander, Napoleon, Caesar, etc.) commanding historical units in some of the world most decisive battles (e.g., Megiddo, Zama, Hastings, Waterloo, etc.) using proven tactics of history. BLT serves as a basic game introducing players to the interaction between army units, leaders and tactics. BLT allows players to command standard troops (e.g, infantry, cavalry, artillery and guard) and special military units (e.g., 300 Spartans, Panzer Army Afrika, etc.) with historic military leaders using real tactics and fog of war–all without any dice. The primary resolution engine for the game is housed in the Tactics Results Chart (TRC), which compares tactics selected by the players and determines losses, if any, of army units.
