Perhaps another game that comes close is Creative Assembly's Warhammer games, they feature a menagerie of roughtly the same fantasy cliche factions, and in large quanitities with varying units, as well as hero units, with an overworld map that you conquer by individual battles taking place in zoomed in instances on the map. It's Total War based, which is very mechanically and stylistically different from traditional RTS games. But you're still having roughtly the same selection of races, dark elves, evil dwarvers, barbarians, demons and all that, and you're fighting skirmish battles in real time on a turn-based overworld map.
