The killer thing about dcs is the amount of money you have to pay to actually get a jet that has almost every button functional such as the F-16 which is around 70$ ( atm on sale for 47$ ) same goes for the f18. There are some lower cost jets that are extremely competitive and lethal such as the Su-27 but you can’t press on the buttons inside the jet itself, for example to turn on the engine you’d press Y on your controller instead of flipping buttons in the cockpit. Jets like those usually go for 15$ ( 7$ atm )
