I know what you mean, look how long it has taken Wargaming to develop World of Warships the free-to-play naval action MMO that plunges players into the era of the 20th century devastating sea wars. Or even World of Warplanes (http://worldofwarplanes.eu/game/). The action MMO game dedicated to the golden era of military aviation.. So long as the games are fun and interesting to play and most importantly free then I guess we will have to wait. As they say all good things come to them who wait.
