For those who enjoyed playing Starcraft and want to see its engine used in a fantasy theme, Primitive Wars is all about that.
More than 3 races, lots of structures and units, real-time strategy with RPG mechanics where your characters evolve by hunting dinosaurs or defeating enemies and not only get stronger but also gain new skills. It has a map editor and a campaign mode that I didn't get to explore much.
I want this game on GOG, as it enchanted me the first time I played it. Although it's available on abandonware, I'd like to see the game on this store receive some improvements so that it's better supported on the latest operating systems.
