The game looks amazing but I agree with "thestrateger" It's way too short for one to really enjoy it. Can't wait to get it. There goes my life.
I've had sleepless weekends playing this best game ever. I lose track of time so quick, I'll start playing it in the afternoon before I know its 3 in the morning. Funny thing is though I have more fun in the first 3 eras once I hit the modern times I get overwhelmed with how much is going on. Which was the other way around for me in Civ IV, not sure what it is either way great game.
