Combat is often a major part of the game, but it is typically abstracted or simplified compared to more tactical wargames.
Examples of grand strategy board games include Risk, Diplomacy, and Axis & Allies.
More realistic grand strategy games, such as Rise and Decline of the Third Reich and Empires in Arms, include specific military units and combat rules.
Computer-based grand strategy games, such as Hearts of Iron, Europa Universalis, and Total War, often have more detailed and sophisticated mechanics and can be played in real-time or with turns.
Some grand strategy games are based on real historical events and can be used to explore alternative scenarios and counterfactuals.
