So much so that we use it as one of our benchmark games. Not only do you get some spectacular units to play with across loads of races and champions, but because magic exists in that setting there is loads of eye candy too. There have been many takes upon the formula but we think that the Warhammer Fantasy setting is comfortably the best of them.
Total War has been impressing us all for years with its combination of overworld turn based strategy and almost 4X style gameplay, and the RTS mode with more units than you can shake a stick at.
