This is an age-old complaint that has gone on since Civ III (when Conquests was released, it included the civs from Play the World); personally, I bought Spain on the day of release and would do so again even if I knew it would be available 18 months later as part of G&K. I don't feel like I've been ripped off; I've had that civ to use all that time, as well as the Inca and the New world scenario which isn't included in G&K.
