if you want to see how something like 'Total War: Warhammer' would play you should check out the Medieval 2 mods 'Call or Warhammer' and 'Sundering: Rise of the witch king'.
I'd highly recommend checking them out. if nothing else it should at least hold you over until CA releases Total War: Warhammer.
