I don't care how much a GREAT game IS to ANYONE. What I do care, is people encouraging business models that aren't worth its value. You can sell anything as much as a person is willing to pay for it. I'm pretty sure that if ciV Deluxe Edition was 150$, you would have bought it.
Modern Warfare 2. 4 maps ( which 2 are from MW 1 ) for 15$
People who buy the same sports game year after year ( Madden 20XX )
etc...
And now this.... Actually if I was with 2k, I WOULD indeed propose this model, 'cause you guys are way too fanatics and pay good $$$ for 1 Civ. Basic game with Egypt, Babylon, China, India for 40$ Each civ for 4$ each, maybe pack them by region or timeline.
Anyhow it's likely, well they should at least, put all pre-order bonus and maps in one DLC like some months down the line for less than 10$. They can keep the soundtrack, as if hours of playing isn't enough to hear it.
