For a while I've wanted to get a broader understanding of air combat history. Earlier this year I tried War Thunder, that game can take you from biplanes to 5th gen. If you have lots of time (or money) to throw at it that is. I got my fill around rank III, which is late war prop planes. For modern 4th gen there are more focused sims like Falcon BMS. I'm hoping to get some recommendations for a sim that covers 1st, 2nd and 3rd gen fighters, which is the blind spot in my understanding. Ideally one sim that covers all 3, covers both red and blue teams and doesn't cost an arm and a leg.
Strike Fighters Project 1 has some early American jets, is it worth getting or does Strike Fighters 2 (with mods and DLC) do everything that 1 does? It's hard to get a read on what the modern IL2 has, it seems to have a lot of DLC. I have the old disc from the 2000s but they are different games. I know DCS has at least some of what I want, but I know that it's not cheap.
Are there any I missed? Do any stand clearly heads and shoulders above the others? Any help to rid me of my analysis paralysis.
