Civ V is just the evolution of Civ IV: some features were lost, new features were added, game play remains the same.

If I was a true fan of the series, I guess I would welcome this evolution of the game. But I am not a true fan. I play the game only once in a while. I should have stayed with Civ IV and not waste 50$ for this version.
On a technical note, I am still wondering why Firaxis does not optimize their game. I have an i7 920 ( with ATI 5870 ) and the game take from 10 to 20 seconds to compute the AI turn, even early in the game!!! The CPU and GPU fans runs at higher RPM than any other games!!!
