The last major release in the DCS line, DCS World, is distributed via a free-to-play model. The core game is available free of charge. We encourage you to check the game out,
but keep in mind that the included modern aircraft, the free Su-25 attack jet, is as different from WWII prop fighters as today’s smartphone from a 1940s Bakelite rotary.
The free to play model, in essence, gives a wider audience a free demo that allows anyone to try the game before they buy it. At the same time, the model accurately reflects immense development costs attached to historically accurate study sims.
