I am so glad to see WBC3 here at GOG! :) This game is definitely one of my all time favorites, with its excellent single player mode, tons of custom character (hero) possibilities, and the possibility to make one's own maps, even. The music is superb, too, and the combination of real time action combat and resource building is a winner. It IS a fantastic mix of RPG and RTS. Get it and have fun! :)
