All in all, Halo Wars is one of the better RTS's available for the Xbox 360. The controls are sharp, the story well written and the gameplay simple and fun. Although it is lacking in certain areas, such as length of single player and the lack of a Covenant campaign, the game more than makes up for it with a high pace and easy-to-handle gameplay style.
It's not Halo 4, but it's a nice change to the usual run and gun style of the Halo series. Still could have done with the Master Chief though.
