Wargame
Player may act as any reasonably sized nation at the time, influencing international politics, economic and military development, and can control battlefields on both strategic and operational levels using combined arms. Frequently used to entertain and simulate alternative history scenarios as well as recreate historical events.
Hegemony – (Longbow Games) – a historical real-time strategy series with real-time tactical combat and supply simulation. Campaigning takes place on a single continuous map where players can zoom between the 3D tactical map and the 2D strategy map at any time.
Command: Modern Operations – (Warfare Sims, 2019) a piece of professional multiplayer wargaming software that is also sold on the commercial market as a single player product. Its primary focus is on allowing the simulation of operational or tactical level real world combat scenarios with real time input. The commercial version comes bundled with some scenarios (in addition to those sold as DLC), however the software's primary focus is the ability to create share one's own scenarios. The creation of a strategic level wargame is possible in the commercial version, however no such scenario has been bundled with the software. Its level of fidelity is represented down to the individual vehicle/infantry squad and it utilizes a regularly updated database of weapons, vehicles, satellites, and equipment used by nearly every nation on the planet from the end of World War 2 to the near future (including some hypothetical entries). Gameplay is a top down 2D map of the Earth, however you can stream your gameplay to Tacview for a 3D view.

Unique game systems: Ace of Aces – (Nova Games, 1980) – this flip-book system is a simulation of aerial dogfighting.
BattleTech – (FASA, 1984) – initially conceived as a board game, it has created a brand that now includes various different boardgames (tactical as well as strategic), miniature game rules, a role-playing game, computer games, flip-book games (by Nova Games) as well as novels and a TV series.
Car Wars – (Steve Jackson Games, 1982) – initially printed as a board game, it quickly evolved to incorporate elements of miniatures games.
Up Front – (Avalon Hill, 1983) – A popular card wargame.
