Query: The best RTS you've never played.

KAG is one of the best games ever made. It is a true classic and one of my all time favorites. One warning is that the Kohan series is very different from typical "RTS" games, in that it is about strategy more than tactics of rapid clicking. It isn't especially difficult to play, but it is more of a thinking man's game, than your usual click fest.
