No this game was poorly optimized and/or Firaxis misled people about the requirements. The game starts out fine but becomes very slow by the 17-1800s and often locks up. My Computer is a 2.4Ghz P4, 512MB Ram and a Geforce 4 64MB Card. Now I know the Gfx card isn't great but I can run Age of Empires III, on maps with 5 or 6 players, with no slow down or lock up problems. I don't understand why this game would be so slow when AOEIII runs fine and it has far better graphics. I don't know what else would cause this game to run slow, I'm sure CIVIII required just as many routine calculations. The game locks frequently if I zoom out to far and I tend to be able to play it well if I zoom in at close range - which is why I think it has something to do with the graphics - which is ridiculous.
The game's minimum Requirements are 256MB Ram and the Recommended is 512. I would hate to try and run this on 256MB, Firaxis should have been honest and made the minimum 512 and recommended 1GB. Bottom line: this game was not well optimized.
