Halo Wars

From what Ive seen and heard, this game seems to be lacking a good amount  of things. The game play seems to be limited in range. I have only played a few Role playing Strategy (RTS) games, and they seem to be pretty decent games. Halo series has seemed to be a good one, but i think that everyone they make it keeps getting worse. Hopefully if any of you guys have the game you can let me know how it is. Anyways here's the trailer for it, enjoy! 

P.S.  The trailer looks really good but what Ive seen from the game play I'm not so sure about the game.
