If the new assets are anything to go by, World of Planes will be pretty stiff competition. Despite an intertitle that says the in-game footage is from an alpha build and not representative of the final product, the clip is pretty impressive. We're treated to a bird's eye view of a squadron of Dauntless divebombers making their way towards a Japanese ship convoy, and there are a couple of obscure aircraft on display (including the Brewster Buffalo and a Rufe, which is basically an amphibious version of the more famous Mitsubishi Zero).
Gaijin seems to have an eye for detail as well (note the operating dive brakes on the Dauntless and the exposed wing rib on an Me 109 above, and in the screenshot gallery below). You can learn more at the game's official website, and don't forget to check out the four-minute trailer after the cut.
