I have been dying for a Fantasy game on the Total War engine for almost a decade, ever since I played Shogun the original title I've wanted a Lord of the Rings style game on the engine. While I am not a big WarHammer fan, I can't wait to see 'Fantasy Total War'.
Man wouldn't it be a bummer if they ended up making a brand new engine and it was more along the lines of that other pretty crap RTS they made which name escapes me... What a let down that would be.
