This might not be the answer you like, but for &quot;serious&quot; fighter jet simulators there is pretty much two options, both of them Windows only.<p>There is still a community around Falcon 4.0 keeping it on life-support. But I wouldn&#x27;t really recommend it as a starting point, considering the significant effort it takes just to get it up and running.<p>The other alternative, more modern and my recommendation, is DCS family. It consits of (gratis) core DCS &quot;World&quot; engine, and a selection of (paid) add-on modules (=planes etc). The nice thing about it is that you can just download DCS: World to try it out, it includes two planes you can fly. The not so nice aspect is that it is quite heavy, both in terms of hardware requirements and in terms of gameplay&#x2F;learning curve. Its very much jumping to the deep end.
