I've enjoyed a few RTSes. RTSes are good for war games, because war is kind of a fast action thing that needs more nuance to time than turns. Of course, I can't usually enjoy multiplayer against half the people I play, because I'm not committed enough to it to find the perfect build order and race through the game with hot keys. Not that it's unfair, but I just think it's lame playing a real time strategy game where their strategy is to "be so super efficient that I can rush them with tanks when they're just building their first soldier". And I'm not committed enough to learn the ways to match their efficiency.
Strangely enough, I always end up committed enough to Civ to do stuff like micromanage my workers ad nauseum, or try to trade with people every turn, or try to hit the shield requirement for a building with no remainder, or lower my science rate on the last turn of research. I guess I'm obsessed... but only obsessed enough to win at Deity, not Sid.
I think I'm a little disillusioned with how much speedy-micromanagement can trump strategy in most games.
