I like RTS games just as the next guy and I am also disappointed that cult franchises such as Age of Empires, Starcraft, Warcraft, etc stopped releasing new games. But I like Turn Based Strategy even more, franchises like Heroes of MIght and Magic, Age of Wonders, Civilization, Total War are my favorite and they are also consistently releasing new games all the time.

Recently I've been playing Total War: Three Kingdoms. Total War is a hybrid game - adventure man is turn based, but battles are real time. I was both skeptical and curious about this approach, but when I tried it I liked it. Then I read somewhere the reason of why the creators did it this way - it's because controlling a huge map with 10+ armies, economy, diplomacy, etc real time would be impossible. So essentially TBS allows the player to go at their own pace which could be one of the reasons of why RTS lost it's popularity.
