On full sim mode it’s realistic and I do mean, realistic modelling every single flight and weapons system.
Im hundreds of hours into the sim and still a relative amateur compared to some.
Check videos of ex A-10 and F-18 pilots etc who play this and say just how incredibly real it is.
Warning as well, this game is a money pit. I’ve spent over £600 on my HOTAS and rudder peddles and built a £2k plus rig to play it on lol.
I shudder to think how much I've spent on my sim racing setup in total.
