Warcraft (one) was a Dune2 clone with crappy pathfinding. But they did add ability to give orders to multiple units at once!
1) The player fulfills the commander role by directly controlling a unit on the battlefield, not in "god mode". The commander unit isn't merely a stylized cursor; it also directly engages in combat.
2) No base-building or tech tree. The number, location, and capabilities of all bases are fixed.
3) No explicit resource gathering. Money is automatically accumulated based on how many bases you control.
It's arguably closer to a MOBA than an RTS.
Most of the successful games that copied Dune 2's format were written by the same studios (Westwood for the C&C franchise, Blizzard for *Craft).
