I hate this viewpoint. DCS isnt built around your personal likes and dislikes. Dismissing other peoples preferences like they matter less than yours is really pretentious. Myself, and MANY others who fly DCS and who dont type in the forums, would love to have a late navy phantom with the excellent radar, as an example (thankfully this is coming) or even an AMRAAM capable one, like my country flew. These arent "fantasy" aircraft. I personally love using cold war aircraft that have excellent fox 1 missiles, for example. They're extremely fun and very effective against modern fighters.
The F16 or F15 are NOT the only fighters that deserve to have their avionics/misiles upgraded. The F16A with the terrible radar is not the only variant that exists, even though it was one of the most common variants built, and according to you, the one that stays "true to the era it was designed in." Military aircraf are NOT static things. The rare exception are things like the F14, which sadly never got more modern radars like every other 4th gen aircraft. There's a good reason wealthy european countries spend multiple millions to upgrade 40 year old aircraft, like the F16. Militaries arent stupid, and they clearly judge these to be worth the money and time invested, and effective against their perceived threat environment, which arent F22s. You dont need an F22 or F35 to fight an SU-27 effectively.
Plus, why complain about more variants? If the devs want to do it and have the required information, why stop them?
