Wargames are strategic games that simulate military operations and battles, often played on a tabletop or through computer software. Players typically control armies or units, making tactical decisions to outmaneuver opponents. These games can range from simple board games to complex simulations that require detailed planning and resource management. Many wargames are based on historical conflicts, allowing players to recreate famous battles or explore alternative outcomes. They can be played competitively or cooperatively, and often involve elements like dice rolling, miniatures, and rulebooks. Popular examples include Warhammer 40,000 and Advanced Squad Leader.
