>Dune/AOE kind of RTS is the most basic form of that
No. They are a variation built on the basic formulas of RTS.
In comparison check Knights of Honor. There is the "get resources, build buildings, build units, attack" recipe (the resource gathering is even more simplistic, and the building tree isn't that complicated), but it is realized in an entirely different way, the gameplay is entirely different.
All the above listed are looks the same, feels the same, plays the same. They are just clones.
