One of the best in (WW2) flightsims I've seen, with varying difficulty that you can customise in details and plenty of mods available to change up your experience. This is the one I'd recommend if anyone wants to get a flightsim.
Grab a joystick(Keyboard flying is possible, but can't beat a joystick), take off and go on a long campaign that can be lengthened further by mods, or just fly around in random battles. The only thing I can think of that this game doesn't do right is the AI, who seems perfectly fine with flying straight at an AA gun in formation while it is shooting them for over 30 minutes straight, and missing every last shot. Other than that, I've not found much wrong with it.
Multiplayer took me a bit to get working, but it's worth it
Good damage modeling, good flight models, and it's pretty to look at as a bonus. If you're into flightsims or want to get into flightsims, grab this one
