Best free "wargame" games

GAME GENRE – A wargame is a type of video game built around the simulation of strategic and tactical warfare. These games often recreate historical settings or military scenarios, putting players in command of armies, navies, or entire nations. From ancient clashes fought with spears and shields to modern conflicts waged with tanks and missiles, wargames span a wide range of eras and battlefields. They typically emphasize realism, strategy, and careful decision-making—rewarding those who can outthink their opponents rather than just outgun them.
