I played Wings of Prey, which happens to be the predecessor to WarThunder and I had plenty of fun with it. Arcadedy as hell, but damn I had fun with it. According to Steam, I have over 170 hours on it over the past 2.5 years. The gameplay wasn't great, but the graphics more than made up for it. Dragging out dogfights where I could easily win just to suck in the beautiful effects and scenery.
One thing about a flight sim with amazing graphics - you can actually play with icons off. In AH, turn icons off and you would have a super difficult time finding anyone. In Wings of Prey, with icons off, I can spot planes as far as the visual range allowed (around 10 miles ish) as vague dots. In a massive furball, it was plenty of fun flying and trying to identify friend from foe.
