World of Warplanes, developed by Wargaming.net, was released in 2013. As a part of the 'World of' series, it shares a player base with World of Tanks and World of Warships. However, it has not maintained the same level of popularity as its counterparts. Being over 10 years old, its player base has likely declined significantly, but it still retains a niche audience interested in historical aerial combat. The game is not an MMO as it lacks a persistent world and large-scale online play typical of MMOs.
