We ought to collaborate with DCS and release the official version of Tejas, something that China/Pakistan did with JF-17, will sell like hot cake.
Also modern variants of Russian jets, like Su-30SM/MKM/MKI, Su-35, Su-34s, Mig-35s. Russian jets are still stuck in 80s models with outdated weapons, and nobody bothers because goras love to keep their superiority over Russian equipment.
Only a few months back, someone released Chinese mod containing J-10s, J-15s, J-16s, J-20s, H-6 long-range bombers and coupled up with HQ-9 SAM (Chinese copy of S400). They pitched them against their "shiny" modern western F-16s, F-18s and got completely obliterated.
