Meh, different games for different people. I liked Wings of Prey (basically WarThunder on single player), generally because it was just good ol fashion fun with quality graphics. Aces High made you work for your kills which in turn led to the fun/thrill of shooting down a plane, WoP let me screw around and do whatever to have fun.
TBH, the only flight sim that had me going was Rise of Flight, just too bad it was a WWI sim. If they had made it WWII, I would've left AH the moment it came out.
