I have thousands upon thousands of hours spent playing the Battlefield and Planetside franchise. Probably hundreds of thousands of kills. However I bet less than 1000 of those are from using air vehicles.
According to Steam I have 344 hours played in War Thunder, most of that being "realistic" mode with the most iconic WW2 planes. BF109, Spitfire, Mustang etc. And most of that time, I had fun. Even spent money on a F2P game. As an old fan I can honestly say that if we got upgraded plane controls to more mimic War Thunder, not only would it be a welcome change, I might even want to try to use them.
And it's not completely out of the question either it seems. As someone who loved tanks in Battlefield 1942 and Battlefield 2, I'm also really excited about the new World of Tanks style control for tanks.
