I've been watching Youtube videoes on a new sim lite called Nuclear Option. It is like SF2 but with fictional (not really, there's a fighter that looks like F-23 Black widow) aircraft and tonight I finally bought it on Steam (17.99). There's no third person view, and IMHO its FM is more phyics based. The dm is insane, its like IL2's dm with inner dm. The dev will have modding capabilities soon and the lead dev wants to see real aircraft flying with and against his fictional aircraft. And yes, there's nuclear weapons from tactical and thermonuclear weapons. They recently put naval ships and an ECM aircraft. Right now I'm having lil trouble of calibrating my throttle. Its a bit sensitive for taixing. I think NO is the SF replacement we are looking for with updated graphics and FM and DM.
Have a look on youtube.
