Well I'm glad there's a reliable thread with a whopping 1 reply about WarThunder being a horrible game.

Anyway. I like WarThunder. It's a good arcade-style flight simulator. Easy to get in to, but a lot of upgrades you can customize your planes with. Good graphics. Good sound. And last I played it they were saying that eventually they were going to work in ground-based combat as well.
If you're looking for something like Microsoft Flight Simulator where you pretty much have to actually be a pilot to play it, then WarThunder isn't for you.
