Digital Combat Simulator World (DCS World) is a free-to-play digital battlefield game focusing on aviation.
The developer's goal is to offer the most authentic and realistic simulation of military aircraft possible. This free download includes a vast mission area of the Caucasus region and Black Sea that encompasses much of Georgia. It also includes a flyable Russian Sukhoi Su-25T ground attack aircraft and the famous WWII North American TF-51D fighter.
Plenty more aircraft, maps, and missions are available for purchase as separate modules including the popular F/A-18 Hornet, the F-14 Tomcat, the A-10 Thunderbolt II, the F-16 Viper, and many more, on top of the well-known Supercarrier expansion, that claims to be the most realistic simulation of the flight deck of a Nimitz-class carrier.
DCS World has been in development for many years as a game-as-a-service, and it's realistic enough that its footage has often been mistaken for real by mainstream news around the world.
