There is a big difference between RTS and turn-based games. I can tell you I've played hundreds of hours of RTS with a group of RL friends. AOE I & II, Age of Mythology, Age of Titans, All the games in the Total War series, Warhammer 40k and the xpacks. And of course the CC series 1 through 5.
I agree with NL that there is a different dimension of tactical "skill" involved with RT. You need to understand the flow of events quicker, analyze what is taking place on the fly and adapt, judge where your actions are needed most, etc.
Then again, RT tactics are far more simplified. There simply isn't enough time once the action starts to do anything too elaborate. Battles can be brutish, ungainly and lack artistry. A simple example is "click and drag" this group to go attack the enemy group. Also, there is a dimension of physical skill needed to know your hot-keys and economize your efforts clicking, scrolling and such.
You also miss out on great drama and heroic efforts during frantic RT battles. These games now are so beautiful, but there is no time to stop and smell the roses other than watching a saved game, which most RTS's have. Even though it is long in the tooth, I still love to lock on a tank at zoom 1 and pan around as it rolls across the ground and engages an enemy. With turn-based you can savor and enjoy the action from each and every vantage point. With RT, that is not possible if you want to ever win a game
I very much enjoy RT games as well as turn-based. For me, the disinterest with SF is the genre. Without getting into a politcal debate, I am turned off with the whole Mid-east thing as this point
Even exculding whats going on these days there, I am a WWII geek. And if not WWII then sci-fi or fantasy. I too will wait for a WWII version. Maybe play TOW when it comes out as well.
