Agreed with WS, as we always seem to do... Wonder why that is.
The average PC (TM) is good enough to run
pretty much any 3D game out there. And by the time CIV is released, the average PC (TM) will have gotten even better. I really don't think we're going to be talking DOOM III material here after all - the 3D isn't the focus of the game, after all.
And eg577, I think it's unfair to assume that Firaxis doesn't think that a better AI is important. Listing "an improved AI over Civ 3!" as an important new feature for the future of the series would be both redundant with the obvious as well as, well... unspactacular. They're obviously not going to
regress any, and since computers are getting better, I think it's safe to assume that it will be better.
Need I repeat the story about how Civ 3's programming team left after a year of work was done and Firaxis had to hire a whole new cadre to take over and save the project.

It's a miracle the thing even loaded, let alone played well. With CIV being made from scratch with a complete team from start to finish (we hope

), I have no doubts that the AI, as well as everything else, will be an improvement over Civ 3.
