I have played them quite a bit over the years although I was more into the combat variety. I was really getting into DCS world flying ops in an F-14 and A-10 and then my gaming rig went kaput. War Thunder has a sim mode that is fairly decent but not as detailed compared to a real sim like DCS. The last time I played it, the sim community had shrunk quite a bit, so I had to play more in "realistic mode" which is keyboard/mouse focused versus sim mode with a stick. War thunder is free, but grindy as hell, so it may be worth giving a try.
Edit: Whoops. I forgot about the IL2 games which have their flaws but are decent games, especially if you get them on sale.
