So not sure how many people are familiar with the World of Tanks game, but the developers made one for planes that kinda sucked.
But this other company Gaijin made another called War Thunder, its free. It has loads of planes from various WWII nations, customization and potential to be a pretty game. Pengxor and a few other friends of mine are playing it and looking for others to join us. The mouse and keyboard controls are really easy and in some cases preferable to the joystick and it looks absolutely beautiful. Check it out.
