MRF The Mech

Have any of you ever wondered if there could be a RTS game with an extensive storyline, really USES strategy, as in you need to plan every move that you would ever make, need to think about it, etc. This is a good kind of game. I was wondering if anyone had ever heard of one, and if you have, please be precise, I only want links/descriptions of good, long, hard, fun RTS games. I have heard of many good ones like STARCRAFT and STARCRAFT II that will be awesome, but SC2 hasn't come out ye
