Nice to hear that I could help a little bit. I made them for 1.15.4 and updated the graphics a little bit, cause in 1.15.4 they look not very nice.
I never had the system to run newer sims, until now. So I used a lot of older simulations, I collected over the years for my homepit (which sadly never really did any mission - only testing the last years). I also used FreeFalcon 5 and 6 which I really loved. Same goes for Strike Fighters Project 1 and 2 or the good old Janes Series like Longbow Anthology, F-15, F-18, USAF Fighters or IAF Fighters.
I think graphics aren't so much important if they are relatively ok, but there has to be a real vegetation (trees, bushes, river beds, hills) and more buildings etc. you could use for NOE flying in an attack helo sim for example. More traffic is also important. I do prefer this much more, as details like better clouds, sun reflections etc.
With the PC power of todays systems you would be able to do tons of such scenery/traffic additions to older simulations like EECH, which is in my opinion better then an overhauled graphics engine, but it seems I'm very lonely with this kind of opinion
