Wargaming developers are working on the company's next combat MMO game featuring Warplanes and its several game modes. With the success of World of Tanks, the developer obviously knows what makes a good combat MMO but that's still not an easy task. Yesterday, they released the part 3 of the World of Warplanes developer diary video series. In this new video they talk about the try and fail experiments they have been doing with World of Warplanes' game modes.
