The problem with DCS is that it is not fun, it is a frustrating game, the AI is unbeatable, it has extreme aim, an amazing reaction capacity, from the ground they kill you just by looking at you, there is no visibility either, in multiplayer you cannot see the planes Enemies, I repeat: they are not seen until they kill you.
The only fun thing in DCS is learning how to fly airplanes and their systems.
Then, when you learn a module and want to put it into practice by playing, it turns out that playing is not fun, because you constantly get killed without even knowing who shot you.
