Anyone mentioning "real time" and strategy in the same sentence deserves a beating.
Oh, and CS is way to twitch-skill based in my oppinion. Anyone can kill everyone with any weapon given enough skill and/or luck. I prefer BF which actually is a tactic shooter, because no amount of luck or skill will be able to crack a tactic there. If you have 10 uber leet shooters with rifles, not one of them will kill a tank. You need a bazooka for that job. Even then I prefer the FH mod to the bunny hopping full auto vanilla variant that reminds me of those plastic soldiers I had in my childhood.
