This is expected to grow to around 300KM by 300KM by the time of completion, whether or not this will influence the amount of players per map is uncertain at this time. Running on the Dagor Engine, the game currently boasts maps that scale from 65 km x 65 km to 100 km x 100 km to 200 km x 200 km in size. In order to orchestrate such battles, an appropriately sized map must be used. The main focus of the various vehicles will be from pre-World War II, to the early years of the Korean War era. The gameplay for War Thunder is heavily simulation based, giving the players the opportunity to experience what it’s like to pilot some of the most influential aircraft, armoured fighting vehicles and ships from important war zones. This was to avoid confusion with the developers’ competition “World of Warplanes”, the name change was also to avoid the confusion that surrounded the game, many players were under the impression that the game’s sole focus was on air based simulations. After some internal debate it was decided that the game should have its name changed from World of Planes to War Thunder. The game saw a name change later in development. IL-2 Sturmovik: Birds of Prey, Apache Air Assault and Birds of Steel are all air based games from Gaijin Entertainment. With the developers, Gaijin Entertainment, having had previous experience in flight based games they have been using their history to help build a better game. The development of War Thunder began in 2009, under the name World of Planes.
