From publisher:Whoever said that historical wargames are boring? Are you tired of wasting hours and hours reading an infinity of tables and using mathematical formulae to discover if you have hit the opponent's soldiers or not? OO is easy to learn and has just the right compromise between realism and playability. Based on the principle of action/reaction, OO doesn't rely on the classic alternate-turn based system and guarantees a fluid and intuitive gameplay. If your aim is to simulate a battle from the Second World War and have fun while you're doing it, then Operation Overlord is the game for you.The new edition by the designer is called Operation World War II.
