I remember a lot of those, and think of them when somebody complains about some minor issue with graphics in DCS
I played A-10 Tank Killer a bit, found it back in the day in a discount bin at a local computer store. But by the time I found it, there were games like Air Warrior with much better graphics, etc. and I was big into the old war birds at the time. I guess it was my first foray into the A-10 and jets though. I still have my Jane's WW2 series tucked away somewhere.
I only recently cleared out a bunch of old games, and am still hanging on to a few for nostalgia, like Jane's and my Warbirds Disc. It's nice to revisit old memories now and then, and get a fresh perspective on how far the genre has come. I don't think I will ever do the work to get them running on win10, just not enough hours in the day.
