It's sad nobody is making RTS games anymore. Now-a-days you'll only find turn based strategy games like Civilization, X-COM, Endless Legend etc. I miss the good old days of AoE and AoM where you could build a city from the scratch, manage your resources, progress through ages, build an army, conquer the world and expand your empire all in real time. I myself have been searching for a new RTS game for a while now and all I found was some old games like Rise of Nations, LotR: The Battle for Middle Earth 2, Warcraft 3 etc. which feel slightly dated now. However, there's one new game that I found which might become the next AoE and that's 0 A.D. but the game is still under development although you can download and play the alpha version now for free if you want. I haven't played it yet, so I can't comment on the quality of the game but telling from the gameplay videos, it looks promising.
